Is It Wrong to Forbid My Friend from Dating My Ex?
AITA for telling my friend not to date my ex? Emotions run high as boundaries are challenged in this complex friendship dilemma.
A 29-year-old woman just got blindsided by the one person she thought had her back, and it all started with her ex and her best friend showing up on each other’s radar way too fast.
OP and her boyfriend of three years split amicably, but the breakup didn’t even have time to settle before mutual friends tipped her off: her friend Amanda, a 30-year-old who knew every detail of her relationship, was suddenly hanging out with and dating OP’s ex.
OP told Amanda the move crossed a line, and now the friend group is split, with Amanda calling her controlling and selfish.
Original Post
So, I (29F) recently broke up with my boyfriend of 3 years. It was an amicable split, but I was still processing the breakup.
Enter my friend (30F), let's call her Amanda. Amanda and I have been friends for over 5 years, and she knew the ins and outs of my relationship.
Fast forward a few weeks after the breakup, and I find out from mutual friends that Amanda and my ex are now hanging out and going on dates. I felt blindsided and hurt.
I reached out to Amanda to express how uncomfortable and betrayed I felt about her dating my ex so soon.
I couldn't shake off the feeling of betrayal, and I told her that it crossed a line for me. Amanda didn't take it well and accused me of being controlling and selfish.
Now our friend group is divided on the issue, with some supporting me and others siding with Amanda. So, AITA?
I honestly don't know if I'm overreacting here.
The emotional fallout from this situation is palpable. The original poster (OP) is feeling not just the sting of heartbreak but also a deep sense of betrayal from someone she considered a close friend. It’s one thing to move on from a relationship, but it’s another to see a friend jump in so quickly. Amanda’s decision to date the OP’s ex just weeks after their breakup raises eyebrows about loyalty and respect in friendships.
Relationships are complicated, and this dynamic highlights how quickly lines can blur. The OP's feelings are valid; it’s natural to feel protective over someone you’ve shared intimate moments with, especially when it feels like the friendship is disregarding those emotions entirely.

OP’s breakup was supposed to be “amicable,” but the moment Amanda and the ex started dating, that “nice” timeline evaporated.
The argument got real when OP reached out to say she felt betrayed, not just hurt, and Amanda snapped back with “controlling and selfish.”
It’s the same kind of mess as the AITA about expressing discomfort to a friend dating your ex without discussing it first.

The Bigger Picture
The original poster's reaction to Amanda dating her ex just weeks after their breakup speaks to the deep emotional ties that often complicate friendships. Feeling blindsided, she’s grappling with a sense of betrayal, particularly since Amanda was privy to the intimate details of her relationship. Amanda's swift move into a romantic relationship with the OP's ex raises questions about loyalty and respect, and her defensiveness suggests a struggle between personal desires and the unspoken boundaries that friendships typically hold. This situation illustrates how quickly the lines can blur when love and friendship intertwine, leading to divided loyalties among their mutual friends.
Her friends might still be “friends,” but nothing feels safe when your ex and your best buddy start dating.
