AITA for Setting Up My Friend with My Ex Whos Now Dating My Sister?

A 28-year-old guy thought his friend group was solid, until he overheard a secret conversation that made everything feel off. He’s got history with Sarah, his ex, and he’s been friends with Max for years too. So when Sarah and Max quietly start dating, it’s not just awkward, it’s personal.

Here’s the kicker, Sarah’s new girlfriend energy is going straight through his family. His sister, Emma, just moved back after college, and she and Sarah clicked at a party he hosted. Now Sarah and Max are together, Emma has no idea, and OP is stuck watching his ex and best friend orbit each other while his sister gets pulled into the same circle.

And once you realize they were hiding it because they feared his reaction, the whole party story suddenly feels like a setup.

Original Post

So I'm (28M) and I've been friends with both Sarah (26F) and Max (30M) for years. Sarah and I used to date, but it didn't work out, and I introduced her to Max, and they hit it off.

Everything seemed fine until I found out that Sarah and Max are now dating, and they didn't want to tell me. For background, my sister, Emma (24F), recently moved back to town after finishing college, and Sarah and Emma met at a party I hosted at my place.

They instantly clicked and have been hanging out a lot. Things got messy when I overheard Sarah and Max talking about how they weren't ready to tell me that they're together because they were worried about how I'd react.

I felt betrayed and hurt. It feels weird seeing my ex and my best friend together.

I confronted Sarah about it, and she admitted they started dating a few weeks ago, but she didn't want to hurt me. Max also apologized and said it just happened naturally.

Emma doesn't know about their relationship. I'm torn between feeling like they should have been honest with me and understanding that they were in a tough spot.

It's awkward, and I don't know how to navigate this situation without causing drama. So AITA?

This situation is a classic case of how tangled friendships can become once romantic interests enter the mix.

OP throws the party where Sarah and Emma instantly connect, then finds out Sarah and Max have been dating for weeks and were keeping it from him.

NTA. That's a tough situation. Your feelings are valid, and it's important to talk openly about this to find a resolution.

The betrayal hits harder when OP overhears Sarah and Max talking about not telling him because they were worried he’d blow up.

YTA. They were probably scared to tell you because they cared about your feelings. It's a delicate situation, but honesty is crucial now.

Also, this feels like a best friend dating OP’s twin brother behind their back.

NAH. Friendships and relationships can get messy. Take some time to process your emotions before addressing this with them.

Comment from u/SilverLiningStorm

NTA. It's normal to feel hurt and confused in this situation.

Sarah admits it started a few weeks ago, Max apologizes like it just “happened naturally,” and OP has to process both the romance and the secrecy at once.

NTA. It's natural to feel hurt and a bit blindsided in this situation. Talk to Sarah and Max calmly to address your concerns and move forward together.
