Is It Wrong to Date Your Best Friends Ex? My Dilemma Explained
AITA for dating my best friend's ex without telling her? OP faces dilemma after falling for ex, risking friendship. Top comments weigh in on the messy situation.
A 27-year-old woman is about to learn that “it just happened” is not always a valid excuse when it involves your best friend’s ex. She and her best friend’s boyfriend-turned-ex connected in a way that felt natural, and now she’s dating him quietly, hoping the secret stays buried.
Here’s the messy part, her best friend (25F) broke up with him eight months ago, said it was amicable, and never mentioned any lingering feelings. The OP (27F) didn’t go hunting for romance, but feelings grew anyway, and she’s stuck between guilt and fear. She knows her friend will find out, and the dread is real because she doesn’t want to lose the friendship over a situation that wasn’t planned.
And that’s how one “low-key” relationship turns into an all-out loyalty test.
Original Post
So I'm a 27F and I recently started dating my best friend's (25F) ex-boyfriend (28M). For background, my best friend broke up with him about eight months ago, and they ended things amicably, or so I thought.
She never mentioned having lingering feelings or issues. I hadn't been looking for a relationship, but we connected in a meaningful way, and it just naturally progressed into something more.
We've kept it low-key, but I know sooner or later she'll find out, and I'm dreading that moment. I haven't told her yet because I'm worried about how she'll react.
I value her friendship, and I don't want to lose her over this. I know dating a friend's ex can be a sensitive topic, but I never expected to have feelings for him.
Should I have told her before things got serious? I can't help but feel guilty about potentially breaking an unspoken rule.
I care about her deeply, but I also care for him. So, AITA in this situation?
I honestly don't know what to do.
The Friendship Test
This situation strikes at the heart of what loyalty means in friendships. The OP’s decision to date her best friend’s ex without a heads-up raises immediate questions about trust and respect. It’s easy to see how feelings can develop, but the lack of transparency makes everything more complicated.
In friendships, there's often an unspoken rule about dating exes, especially when feelings are still raw. The OP is navigating a moral grey area that many can relate to—how do you balance personal happiness with the potential fallout on those you care about? It’s a tightrope walk that can leave both parties feeling betrayed or hurt.

She kept it low-key with her best friend’s ex, but eight months is still plenty of time for old emotions to resurface.
The OP didn’t tell her best friend before things got serious, even though the breakup was supposedly “amicable.”
It also echoes the dilemma in the AITA post where someone asked a friend to stop dating her ex after sharing intimate relationship details.
The Community's Divided Opinions
The Reddit community's reactions highlight just how complex relationships can be. Some commenters might empathize with the OP, understanding that love can be unpredictable and often defies social norms. Others, however, are quick to call out the ethical implications of her actions, suggesting that she should have prioritized her friend’s feelings over her own budding romance.
This division reflects a broader societal debate about the boundaries in friendships and romantic relationships. There's no one-size-fits-all answer, and that’s what makes this story so relatable. It forces readers to think about their own experiences and where they draw the line when it comes to love and loyalty.

When she imagines the moment her best friend finds out, it’s not the romance she’s worried about, it’s the trust she might shatter.
That’s where the Reddit comments start splitting, because some people can’t separate feelings from the unspoken “don’t date my ex” rule.

The Takeaway
This dilemma serves as a reminder of the complex interplay between friendship and romance. As OP navigates this tricky situation, it raises the question: how far are we willing to go for love, and at what cost to our friendships? It’s a conversation worth having, as many of us have likely faced similar crossroads. What would you do in OP’s shoes?
The Bigger Picture
The OP’s decision to date her best friend's ex-boyfriend speaks volumes about the complexities of modern relationships. While she claims their romance developed naturally, the underlying tension stems from the unspoken rules that often guard friendships, especially concerning exes. Her hesitation to inform her friend suggests a deep awareness of the potential fallout, indicating that her feelings for the ex may have overshadowed her loyalty to her friend. This situation spotlights the struggle many face when balancing personal desires with the expectations of their social circles.
She might end up with a boyfriend, but losing her best friend would hurt way more.
