Is it Wrong to Date a Friends Ex? AITA for Keeping it a Secret?

A 28-year-old woman refused to say one simple sentence to her best friend, and now her entire love life is wrapped in awkward silence. She met Mark at a party, clicked with him fast, and things turned into a real relationship.

But Mark is not just any guy, he is her friend’s ex-boyfriend. They broke up about two years ago on good terms, they still run into each other, and they even stay friendly in the same social circles. The complication is brutal: OP is dating Mark, yet she has not told her friend. She’s dodging the topic, keeping the relationship secret, and trying to avoid hurting feelings, even though things are getting serious.

Now the question is whether keeping it quiet is protecting the friendship or quietly setting it on fire.

Original Post

I (28F) recently started seeing someone new - let's call him Alex. Alex is amazing, but here's the catch: he's my friend's (29F) ex-boyfriend, Mark.

Mark and I met at a party a few months ago, hit it off, and things naturally progressed into a relationship. For background, Mark and my friend dated about two years ago, and they ended things on good terms.

They're still friends and occasionally h**g out in the same social circles. Here's where the drama starts - I haven't told my friend that I'm now dating Mark.

I know this is a sensitive situation, but I didn't want to hurt her feelings. I've been avoiding the topic when we chat and keeping our relationship a secret from her.

I'm torn between wanting to be honest with her and not wanting to ruin our friendship over a guy. So, AITA for not telling my friend that I'm dating her ex-boyfriend, even though we're getting serious?

I honestly don't know if I'm wrong here.

This situation really highlights the murky waters of friendship dynamics. The OP started dating Mark, who had previously dated her friend, and the relationship blossomed without an obvious reason for secrecy. But the ethics of dating a friend's ex can be incredibly nuanced. It raises questions about loyalty, especially since friendships are often built on trust and honesty. If the OP had been open about her feelings for Mark, would that have altered the friendship or even prevented this dilemma altogether?

The OP's choice to keep it under wraps suggests a deeper insecurity about how her friend might react. This secrecy could indicate that she fears the potential fallout more than she values transparency. It’s fascinating how a secret like this can create a rift, even when the intentions might be innocent.

OP met Mark at a party, and the connection felt so natural that telling her friend never seemed like the first move.

NTA - If they broke up amicably, there's a chance she might be cool with it. But honesty is key, she deserves to know. Good luck, OP!

You gotta spill the beans, OP. Secrets like these always come out and it'll be worse the longer you wait. YTA if you keep this from your friend.

Sis, you're playing with fire here. Being upfront is scary, but necessary. She'll appreciate your honesty more than the deceit. It's gonna be rough, but that's life.

This is a delicate situation, OP. Mark being your friend's ex adds layers of complexity. While it's tough, telling the truth is the right move. Good luck!

Since Mark and the friend ended things amicably and still hang out in the same circles, OP assumed her friend might not react badly, which is why the secret feels safer than the truth.

If she's a true friend, she'll understand. But keeping this from her will only make things worse. Confess sooner rather than later, honesty is everything. NTA but tread carefully.

This is the same kind of mess as the AITA post where the best friend’s ex dating was kept secret, sparking betrayal with mutual friends.

I get why you'd be hesitant, but secrets have a way of blowing up at the worst times. You're walking a tightrope, OP. NTA for now, but honesty is your best bet. Good luck!

YTA if you keep this under wraps. The longer you wait, the worse it'll be when she finds out. Rip off the band-aid and have that awkward convo. It's necessary for your friendship.

The moment OP starts “avoiding the topic” in chats, the friendship stops being casual and starts feeling like a lie she has to maintain.

It's a tough spot to be in, OP. But honesty is crucial in friendships. Prepare for a potentially rocky conversation, but keeping secrets isn't sustainable. NTA if you come clean.

Comment from u/CoffeeCraze101

Oof, that's a sticky situation. Your heart's in the right place, but you gotta tell her soon. The longer you wait, the more it'll hurt. YTA if you keep this from her.

Comment from u/SleepyPanda456

The truth will set you free, OP. It's gonna be a tough convo, but it's necessary. Keeping it from her won't end well. Be brave and come clean. NTA for now, but time to come clean.

As their relationship gets serious and Mark becomes more than a fling, the silence between OP and her friend becomes the real drama, not the breakup history.

We're curious to hear your perspective. Share your thoughts in the comments.

The Reddit community's response to this post really reveals a split in how people view loyalty among friends. Some users are quick to defend the OP, arguing that since the relationship with Mark ended, she has every right to pursue her happiness. Others, however, feel that even if the relationship ended, the emotional residue left behind makes it off-limits. This tension between personal freedom and perceived betrayal is what makes the story resonate with so many.

It’s also interesting to see how people project their own experiences onto the situation, often leaning into their biases. For some, dating a friend's ex feels like a violation of an unspoken code, while others view it as a natural progression of relationships. This variety of opinions shows how subjective friendship rules can be and how they vary widely from one person to another.

Where Things Stand

This story serves as a reminder that friendship and romance often collide in unexpected ways. As readers weigh in on whether the OP was right to keep her relationship a secret, it raises the question: how far should we go to protect our friendships when pursuing new love? What would you do if you were in the OP's shoes?

The original poster's decision to date Mark, her friend's ex, reflects a common struggle between personal happiness and loyalty to friendships. Despite Mark and her friend ending things amicably, the OP's choice to keep the relationship a secret suggests she's more concerned about the potential fallout than the honesty that could strengthen their bond. This tension highlights how complicated friendship dynamics can be, especially when romance enters the picture, and raises the question of whether it's worth risking a friendship for love. Ultimately, her dilemma encapsulates the messy realities of navigating relationships within social circles.

Keeping Mark hidden might feel gentle today, but it’s the kind of secret that can turn a good breakup into a permanent rift.
