Friend Betrays Me: AITA for Not Supporting Friend Dating Cheating Ex?

A 28-year-old woman refused to pretend her ex-boyfriend was suddenly “fine” just because her friend wanted to date him. And honestly, it’s not even a petty ex-drama situation, it’s a loyalty test with real emotional receipts.

Her friend Sarah, 26, knows exactly what happened with Alex, 30. Alex cheated on the OP with a coworker, and she told Sarah all the messy details while it was happening. But now Sarah is dating Alex anyway, claiming he changed, and she keeps bringing him along to hangouts like nothing ever broke.

The awkward group meetups aren’t just uncomfortable, they shove the cheating back into the OP’s face, and now she’s wondering if Sarah even cares about the friendship she promised to protect.

Original Post

I (28F) have a friend, let's call her Sarah (26F), who recently started dating my ex-boyfriend, Alex (30M). Sarah knows all about my history with Alex; he cheated on me with his coworker before we broke up.

It was a painful experience for me, and I confided in Sarah throughout that time. Despite knowing how much I was hurt by Alex, Sarah decided to give him a chance.

She claims that he has changed and deserves a second shot at love. I couldn't believe she would choose to date him knowing everything he put me through.

I expressed my concerns to Sarah, telling her how uncomfortable and betrayed I felt by her decision. Sarah brushed off my feelings, saying that it's her life and her choice.

She accused me of being possessive and trying to control her happiness. I never told her to break up with him, just shared my honest feelings.

Now, whenever we h**g out as a group, Sarah brings Alex along. It's awkward for me to be around them and witness their budding relationship.

I feel like Sarah prioritized her newfound romance over our friendship and my feelings. Seeing them together brings back painful memories and makes me question Sarah's loyalty.

Shouldn't she have considered my emotions before pursuing a relationship with my ex who hurt me deeply? So AITA?

The Betrayal Cuts Deep

This scenario strikes a nerve because it’s not just about a love triangle; it’s about loyalty and trust. The OP’s ex, Alex, didn't just cheat; he shattered a relationship that was supposed to be built on love and respect. When Sarah, the friend, decides to date him, it feels less like a romantic choice and more like a personal betrayal to the OP. Readers can relate to the visceral pain of watching someone you care about prioritize romantic interests over friendship.

Moreover, Sarah’s decision pushes the boundaries of what's acceptable in friendships. It raises questions about whether loyalty can survive such a betrayal and if a line is crossed when friends choose their own happiness at the expense of another's heartbreak.

When Sarah brushed off the OP’s hurt and accused her of being “possessive,” the friendship felt like it got flipped upside down fast.

NTA, your friend should have respected your feelings, especially after everything you went through with that guy.

I can't believe Sarah would do that to you! That's such a betrayal. NTA for feeling hurt and confused in this situation.

Comment from u/CoffeeBeanAddict99

Girl, you are absolutely NTA. Your friend is crossing a major boundary by dating your ex, who broke your trust. That's not cool at all.

Comment from u/AdventureSeeker42

I had a friend do the same thing to me. It's such a tough situation. OP, your feelings are valid, and Sarah should have been more understanding. NTA.

But the real gut punch is the group hangouts, where Sarah brings Alex along and the OP is forced to watch them spark up in real time.

Comment from u/CuriousCatLady

Urgh, Sarah's behavior is so insensitive. It's like she's putting her own desires above your feelings. Definitely NTA in this messy situation.

Also, if you felt like you were walking a tightrope, see the AITA where someone gave dating advice to their best friend, then asked them out.

Yikes, Sarah is being super selfish here. NTA for feeling hurt and betrayed. Friends should prioritize each other's emotional well-being over fleeting romances.

Comment from u/StarryNightSky89

OP, your friend should've been more empathetic towards your past trauma. NTA for feeling the way you do. Just remember to take care of yourself first in this tough situation.

Every time Alex shows up after cheating on the OP, it turns “second chance” talk into a daily reminder of what Sarah already knew.

Comment from u/BookWormGal

This is a huge red flag on Sarah's part. Friends should uplift and support each other, not date each other's exes, especially ones who cheated. NTA all the way.

Comment from u/SleepyPanda_52

So sorry you're going through this, OP. Sarah's behavior is a major breach of trust. You have every right to feel hurt and betrayed. NTA.

Comment from u/GamerGirlForever

OP, your friend is so out of line! Dating your ex, especially after what he did to you, is beyond disrespectful. NTA for feeling hurt and questioning her loyalty.

Now the OP is stuck questioning Sarah’s loyalty, because Sarah is choosing romance over the pain she heard firsthand.

Divided Opinions on Friendship

The community's reaction to this post showcases the complexity of friendships. Some readers support the OP's decision not to back Sarah, emphasizing that dating an ex—especially one known for infidelity—crosses an unspoken line. Others argue that love is unpredictable and friendships should adapt accordingly, suggesting that Sarah deserves a chance at happiness.

This division illustrates the conflicting ideals of loyalty versus individual happiness. It's a moral grey area where one person's betrayal can lead to another's chance at love, leaving the OP in a painful position. The debate highlights how personal experiences shape perceptions of right and wrong in relationships.

The Bigger Picture

This story resonates because it encapsulates the messy reality of human relationships, where boundaries are often tested and emotions run high. The OP's struggle with betrayal and loyalty represents a dilemma many can relate to. As friendships evolve, how do we navigate the tricky waters of love and loyalty? This situation begs the question: can a friendship survive after one party chooses to pursue a relationship with a known betrayer?

The Bigger Picture

This situation highlights the emotional turmoil that arises when a friend prioritizes a romantic interest over loyalty.

The OP isn’t the villain for not cheering on the man who broke her, even if Sarah insists it’s “her life.”
