My Best Friend Slept with My Fiancé, Then Asked Me to Be Her Maid of Honor

I’m writing this from my apartment at 2 AM because I can’t sleep and I genuinely need to know if I’m losing my mind. Six months ago, I discovered my best friend and my fiancé were having an affair. Three weeks ago, she called to tell me they’re engaged. Yesterday, she asked me to be her maid of honor.

I’m not joking. I wish I were joking.

Everyone in my life has a different opinion on what I should do, and I’m so emotionally exhausted that I can’t tell what’s real anymore. So I’m turning to internet strangers because at least you don’t have a stake in this nightmare.

The Setup

I’m 31 years old. My former best friend “Amber” is also 31—we’ve been best friends since we were 14 years old. Seventeen years of friendship. She was the sister I never had. We did everything together. We knew each other’s families, shared every secret, planned our futures around staying close to each other.

My ex-fiancé “Ryan” is 33. We’d been together for five years, engaged for eight months. The wedding was planned for this past October. I’d already bought my dress. We’d put deposits down on everything. My life was planned out, and I was genuinely happy.

Amber was my maid of honor, obviously. She’d been helping me plan the wedding, coming to dress fittings, organizing my bachelorette party. She and Ryan got along great, which I loved. I wanted my future husband and my best friend to like each other.

I’m an idiot.

The Discovery

Six months ago, I came home early from a nursing shift. I’m a nurse and my schedule is unpredictable—sometimes I get sent home early if the unit is overstaffed.

I walked into my apartment (Ryan and I lived together) and immediately knew something was wrong. There were women’s shoes by the door that weren’t mine. I heard voices from the bedroom.

I should have known right then. But my brain couldn’t process it. I actually thought maybe Ryan had let his sister come over to drop something off.

I opened the bedroom door.

Ryan and Amber were in my bed. MY bed. The bed I slept in every night. The bed where Ryan had proposed to me.

They saw me immediately. Amber screamed. Ryan jumped up, scrambling for his boxers. And I just stood there, frozen, unable to process what I was seeing.

“It’s not what it looks like,” Ryan said.

I actually laughed. Like a crazy person, I laughed. Because what else could it possibly look like?

Amber was crying, grabbing her clothes. “I’m so sorry. I’m so, so sorry. We didn’t mean for this to happen.”

“How long?” I asked. My voice didn’t sound like my own.

They looked at each other. That look told me everything.

“How. Long.”

“Three months,” Ryan said quietly.

Three months. A quarter of a year. While I was planning our wedding. While Amber was helping me choose centerpieces and addressing invitations.

“Get out,” I said to Amber. “Get the fuck out of my apartment.”

She grabbed her stuff and ran. Ryan tried to talk to me, tried to explain, but I told him if he didn’t leave immediately I was calling the police. He left.

I called my mom. Then I threw up. Then I called off work for the next three days and didn’t leave my bedroom.

The Immediate Aftermath

The next week was a blur of canceling wedding vendors, returning engagement rings, and fielding calls from confused family members and friends.

Everyone was shocked. Our families had been excited about the wedding. Our friend group was tight-knit. Nobody saw it coming.

Amber tried to call me 47 times in the first week. I counted. She sent hundreds of texts:

“Please let me explain” “I never meant to hurt you” “It just happened, we couldn’t help it” “Our friendship means everything to me” “I’m in love with him, I didn’t plan this” “You deserve better than Ryan anyway” “Can we please talk?”

I blocked her on everything.

Ryan’s messages were similar:

“I’m so sorry” “Amber and I never planned this” “I do love you, but I fell for her” “I’m a terrible person, I know” “Can we at least talk about dividing our stuff?”

I blocked him too.

My family was furious on my behalf. My dad, who’d loved Ryan, said he never wanted to hear his name again. My mom kept saying, “I can’t believe Amber would do this. I trusted her.”

Our mutual friends were split. Some immediately cut off both Ryan and Amber. Others tried to stay neutral, which felt like a betrayal in itself. A few actually defended them, saying “you can’t help who you fall in love with.”

I cut off anyone who said that.

The Healing Process

I won’t lie—the first three months were hell. I cried every day. I went to therapy twice a week. I lost fifteen pounds because I couldn’t eat. I had to take a leave of absence from work because I couldn’t focus.

My therapist helped me work through the double betrayal. Losing your fiancé is devastating. Losing your best friend of seventeen years is devastating. Losing both at once to each other? That’s a special kind of trauma.

I went through all the stages: denial (maybe it was just a one-time mistake), anger (I hoped they’d both get hit by a bus), bargaining (maybe if I’d been a better girlfriend/friend), depression (I’ll never trust anyone again), and eventually… not quite acceptance, but resignation.

By month four, I was doing better. I’d gone back to work. I was seeing friends again. I’d even been on a few dates. I’d moved into a smaller apartment that had no memories of Ryan. I was rebuilding my life.

I thought the worst was behind me.

Then Amber’s mom called.

The Phone Call

Amber’s mom, “Patricia,” has known me since I was fourteen. She’s like a second mother to me. Or she was.

“Honey, I know things are complicated right now,” Patricia said. “But I need you to know that Amber is really struggling. She misses you terribly.”

“She should have thought about that before she slept with my fiancé,” I said.

“I know, sweetheart. What she did was wrong. But she’s in so much pain. She lost her best friend. Can’t you two at least talk?”

“No.”

“She’s in therapy. She’s working on herself. She knows she made a terrible mistake.”

“Good for her.”

“She’s also… she’s very happy with Ryan. They’re really in love.”

My stomach turned. “Is there a point to this call?”

“I just think… they’re going to be together. They’re serious. And you and Amber have been friends for so long. Maybe there’s a way to heal from this and all move forward.”

“Move forward? Are you seriously asking me to forgive my best friend for fucking my fiancé so we can all be friends again?”

“I’m asking you to consider that people make mistakes, and that love is complicated.”

I hung up.

I should have known that call was a warning of what was coming.

The Engagement Announcement

Three weeks ago, I got a text from a number I didn’t recognize:

“Hi, it’s Amber. I know you blocked me, but I got a new number because I really needed to talk to you. Ryan and I are engaged. I wanted you to hear it from me first.”

I stared at that message for ten minutes.

They’d been together for nine months total. Six of those months were while Ryan was still with me. And now they were engaged.

Before I could stop myself, I responded: “Congratulations. I hope you’re very happy together. Please don’t contact me again.”

“I understand you’re hurt. But I hope someday we can talk about everything. I miss you.”

“You don’t get to miss me. You made your choice.”

“I didn’t choose Ryan over you. I fell in love. It wasn’t about choosing.”

“You fucked my fiancé in my bed. You helped me plan a wedding to a man you were sleeping with. You absolutely made a choice. Multiple choices. Leave me alone.”

I blocked the new number.

I thought that was the end of it. I was wrong.

The Maid of Honor Request

Yesterday, I got a letter in the mail. Hand-written, five pages long, from Amber.

I should have thrown it away. But I read it.

The letter was a mix of apology, explanation, and justification. She was “sorry for the pain” but “couldn’t deny her feelings.” She and Ryan had “an instant connection” that was “undeniable.” She’d “never felt this way about anyone.” Their love was “real and deep and meant to be.”

She talked about our seventeen-year friendship. All the memories, all the moments we’d shared. How much I meant to her. How she’d been “living in agony” without me in her life.

And then, in the final page, she wrote:

“Ryan and I are getting married next June. I know this is a lot to ask, but you’ve been my best friend for more than half my life. I can’t imagine getting married without you there. Would you consider being my maid of honor? I know it’s unconventional, but our friendship means everything to me, and I want you by my side on the most important day of my life. I’m enclosing an invitation to our engagement party next month. I really hope you’ll come. Love always, Amber.”

I read that paragraph three times to make sure I wasn’t hallucinating.

She wants me to be her maid of honor. At her wedding. To my ex-fiancé.

I actually laughed out loud. Then I cried. Then I got angry. Then I got confused.

Because a part of me—a small, stupid part of me—felt touched that she’d asked. That after everything, she still considered me her best friend.

But the larger, rational part of me knows this is absolutely insane.

The Reactions

I’ve told several people about this request, and the reactions have been all over the map.

My mom: “That girl has lost her mind. She has some nerve asking you to celebrate her relationship with YOUR ex. Don’t even respond.”

My sister: “This is next-level audacity. But honestly? Kind of iconic. You should go to the engagement party and cause a scene.”

My therapist: “How do YOU feel about it? What would saying yes accomplish for you? What would saying no accomplish?”

My coworker: “Absolutely not. That’s disrespectful and delusional. Block her completely.”

My cousin: “I mean… seventeen years of friendship is a long time. Maybe she genuinely wants to repair things?”

My new friend from a support group: “She’s manipulating you. She wants you there to assuage her guilt. Don’t fall for it.”

But then there are the opinions that mess with my head:

One of our mutual friends who’s stayed in touch with Amber: “She really does miss you. She talks about you all the time. I think she genuinely believes you could all move past this.”

Amber’s sister: “Amber made a mistake, but she’s not a bad person. She loves Ryan, and she loves you. Can’t all three of you find a way to be adults about this?”

A Reddit comment on a different post I made: “Life is short. If you miss your friend, maybe consider it. Holding onto anger only hurts you.”

Even my own brain sometimes thinks: Do I miss Amber? Yes. Was our friendship real and valuable? Yes. Is there any universe where I could watch her marry Ryan and be happy for them? …Maybe?

And that’s what’s making me feel crazy.

The Complexity

Here’s what’s messing me up: it’s not as simple as “they’re terrible people and I hate them.”

I’ve had six months to process. I’ve done a lot of therapy. And I’ve come to some uncomfortable realizations:

  1. Ryan and I had problems I didn’t want to admit. He’d been pulling away for months before I caught them. I was so focused on the wedding that I didn’t notice our relationship deteriorating.
  2. Amber and Ryan do seem genuinely in love. From what I hear through mutual friends, they’re happy together. They’re not just having a fling—they’re building a real relationship.
  3. I don’t actually want Ryan back. Even if Amber disappeared tomorrow, I wouldn’t take him back. The trust is gone. The love is gone. I’ve moved on emotionally from him.
  4. I DO miss Amber. Seventeen years of friendship doesn’t just evaporate. I miss our late-night calls. I miss having someone who knows my entire history. I miss my best friend.
  5. Part of me understands how affairs happen. Not excusing it—but understanding that people can fall in love unintentionally, that attractions develop, that life is messy.

But then I think: They had an affair. They lied to me for three months. They had sex in my bed. Amber helped me plan my wedding while sleeping with my groom.

And any sympathy I’m feeling evaporates.

The Practical Considerations

If I’m being completely practical, here are the considerations:

Reasons to say no:

  • It’s absolutely insane to be in your ex-fiancé’s wedding
  • It would be emotionally devastating to watch them get married
  • Everyone would judge me (and probably them)
  • It would look like I’m condoning what they did
  • My family would be furious
  • I’d have to pretend to be happy for them
  • It would probably set back all my healing progress
  • It’s asking too much of me

Reasons to potentially consider it:

  • I do miss Amber and our friendship
  • Seventeen years of history is significant
  • I’ve genuinely moved on from Ryan romantically
  • It might bring closure to officially witness them together
  • Saying yes would be the bigger person move
  • Life is short and holding grudges is exhausting
  • Maybe forgiveness is possible?
  • Our mutual friends could stop being caught in the middle

But even writing that second list makes me feel stupid. Am I really considering this?

What Amber Said

I did something I probably shouldn’t have. I unblocked Amber’s new number and texted her:

“Did you seriously ask me to be your maid of honor?”

She responded immediately: “Yes. I know it’s a lot. But I meant every word in that letter.”

“You want me to stand next to you while you marry my ex-fiancé.”

“I want my best friend with me on the most important day of my life.”

“I’m not your best friend anymore. You destroyed that.”

“Friendships can heal. Ours can heal. I know it.”

“You slept with Ryan in my bed while wearing the bridesmaid dress you were supposed to wear in MY wedding. Do you understand how deranged this request is?”

Long pause. Then: “I’m not asking you to forget what happened. I’m asking if you can forgive. Eventually. Someday. And if you can, I want you there.”

“Why? So you can feel less guilty?”

“No. Because I love you. Because our friendship mattered. Because I’m a better person with you in my life.”

“You should have thought about that before you betrayed me.”

“I think about it every day. I made the worst mistake of my life. But I also fell in love. Both things are true.”

I didn’t respond after that.

The Audacity

Can we just acknowledge the absolute AUDACITY of this request?

She didn’t just ask me to come to the wedding. She asked me to be the MAID OF HONOR. To plan her bachelorette party. To give a speech about how wonderful she and Ryan are together. To help her get ready on her wedding day. To stand next to her at the altar while she marries the man who was supposed to marry me.

The entitlement is breathtaking.

And yet…

And yet part of me is almost impressed by her boldness? Like, it takes a certain kind of confidence to blow up someone’s entire life and then ask them to celebrate your happiness.

Or maybe it’s not confidence. Maybe it’s delusion. Maybe she’s so deep in her own narrative—that this is a great love story, that they couldn’t help falling for each other, that true love conquers all—that she genuinely doesn’t see how insane this is.

Or maybe she does see it, and she’s testing me. Testing if I’ve really forgiven her. Testing if our friendship can survive anything.

I don’t know. And not knowing is driving me crazy.

My Current State

I’m torn in a way I didn’t think was possible.

The rational part of my brain is screaming: “Absolutely not! This is insanity! You owe her nothing! Protect yourself!”

But there’s this small, quiet part of me whispering: “What if? What if forgiveness is possible? What if you really have moved on? What if you could salvage something from the wreckage?”

I find myself thinking about our friendship. The good parts. The seventeen years before everything went to hell.

I think about Amber at fourteen, crying in my bedroom after her first heartbreak.

I think about us at eighteen, taking our college acceptance photos together.

I think about her holding my hand during my dad’s cancer scare when I was twenty-three.

I think about hundreds of inside jokes, shared memories, moments that meant everything.

Can all of that really be erased by three months of betrayal?

My therapist says that’s the wrong question. The right question is: “Can you be in her life again without it damaging you?”

And I honestly don’t know the answer.

The Pressure

Since that letter arrived, the pressure has been mounting.

Amber’s mom called again. “Just come to the engagement party. You don’t have to commit to anything else. Just see them together. See how happy they are. Maybe it will help you heal.”

Our mutual friend group is split. Some think I should cut them off forever. Others think I should “at least hear them out.”

One friend said, “Look, what they did was wrong. But they’re together now. They’re getting married. At some point, you need to accept reality and decide if you want to be part of their lives or not.”

Another said, “If you go to that wedding, you’re telling everyone that what they did was okay. You’re giving them permission to have betrayed you.”

Even my own family is divided. My mom says absolutely not. My dad says it’s my choice. My sister says I should go and object during the ceremony (she’s joking, I think).

Everyone has an opinion. And I still don’t know what mine is.

The Real Question

I think what I’m really struggling with is this: What does forgiveness look like?

Does forgiveness mean pretending it never happened? Does it mean being in their wedding party? Does it mean staying friends while maintaining boundaries? Does it mean wishing them well from a distance?

Can I forgive Amber for the affair but still say no to being her maid of honor?

Can I acknowledge that people make mistakes while still protecting myself from further hurt?

Can I miss my friend while recognizing that our friendship can never be what it was?

I genuinely don’t know.

What I do know is that I’m exhausted. I’m tired of being angry. I’m tired of people asking me if I’ve forgiven them yet. I’m tired of explaining why this is complicated.

Part of me wants to just say yes—not because I want to, but because it would make everything easier. The pressure would stop. People would stop asking. Amber would stop reaching out. I could just get through the wedding and then decide how much contact I want after.

But another part of me knows that “making things easier” is the wrong reason to do anything.

So Here’s My Question

Am I insane for even considering this?

Should I: A) Ignore the request entirely and maintain no contact B) Respond with a definitive no and explain why C) Go to the engagement party to see how I feel D) Actually consider being in the wedding E) Something else entirely

My best friend slept with my fiancé. Now she’s marrying him and wants me to be her maid of honor.

Is there any universe where this is okay? Or am I losing my mind for even debating it?

What would you do?


UPDATE (24 hours later):

Holy shit. I did not expect this response. Twenty thousand comments. I’ve been reading for hours and crying and laughing and feeling validated and also called out.

A few things:

  1. I’m not going. Reading your responses made me realize I was confusing “forgiveness” with “people-pleasing.” I was so focused on what everyone else wanted that I forgot to ask what I want. And I don’t want to be in that wedding.
  2. I drafted a response to Amber. It basically says: “I appreciate that you value our friendship, but I can’t be part of your wedding. What you’re asking is too much. I wish you and Ryan well, but I need to move forward separately from you both.”
  3. I’m blocking her again after I send that. And this time I’m blocking her family too.
  4. My therapist is proud of me. We had an emergency session this morning after I read the comments and she said I’m finally putting my own needs first.
  5. To everyone saying Amber is a narcissist: Yeah. I’m starting to see that. Her letter was all about what SHE needs and wants. Not once did she acknowledge the full weight of what she did to me.

Thank you all for the reality check. I needed it.
