Best Friend Betrayal: AITA for Refusing to Sign Lease After She Dated My Ex?

A 28-year-old woman refused to sign a lease with her best friend after the friend quietly started dating her ex. And when the truth dropped a week before move-in, it was not a cute “oops” moment, it was a full betrayal hangover.

Sarah and OP have been best friends since college, they even talked about living together, and they finally found the “perfect apartment.” Then, right before the lease signing, Sarah confessed she’d been dating OP’s ex-boyfriend for months, even though OP and her ex broke up on good terms and the whole topic still stings.

Now the friend group is split, and OP is wondering if saying no to the lease makes her the bad guy.

Original Post

I (28F) have been best friends with Sarah (27F) since college. We always talked about getting a place together, and we finally found the perfect apartment.

However, a week before we were set to sign the lease, Sarah dropped a b**b on me. She confessed that she's been dating my ex-boyfriend for the past few months.

For background, my ex and I broke up on good terms, but it was still a sensitive topic for me. I never imagined Sarah would do this behind my back.

I was blindsided and hurt by her betrayal. I told Sarah I couldn't live with her after what she did.

She begged for forgiveness, claimed it was all a mistake, and said she'd end things with him. But I couldn't shake off the feeling of betrayal.

Despite her pleas, I made the decision not to sign the lease with her. Sarah is now scrambling to find a new roommate, and our friend group is divided on whether I made the right call.

So AITA?

Why This Request Crossed a Line

This situation really highlights the complexities of friendship boundaries. The OP's best friend, Sarah, didn’t just date the OP’s ex; she kept it secret for months while they were planning to move in together. That’s a huge breach of trust. It's one thing to feel attracted to someone, but hiding it from a close friend, especially when that friend is still processing a breakup, feels like a betrayal of loyalty.

Readers can’t help but feel for the OP, who’s left questioning the very foundation of their friendship with Sarah. Will their bond ever recover from this? It’s a situation that many have faced, making it relatable and sparking heated debate about what constitutes a true friend.

The Complicated Nature of Exes

Dating an ex is never straightforward, but doing so behind a friend's back adds layers of complexity. The OP likely still has feelings tied to their past relationship, which means Sarah’s actions could trigger a lot of unresolved emotions. The tension here is palpable; it’s not just about the ex, but also about Sarah’s disregard for the OP’s feelings.

This kind of scenario often leads to divided opinions. Some may argue that dating an ex is fair game, while others see it as an unspoken rule that should never be crossed. The Reddit community's reactions reflect this divide, as many weigh in on whether Sarah's actions were acceptable or downright deceitful.
