I Told My Best Friend’s Ex That He’s Been Seeing Other Girls Without Telling Her I Did It and Now Everything Feels Complicated
Picture a college morning: dogs near the main entrance, students stopping to pet them, and a casual conversation that turns into an emotional landmine. That’s exactly what happened to a Reddit user calling themselves u/Most_Friend5376, who shared the messy fallout on r/AITAH after a chance encounter with his best friend’s ex. He went to pet a dog, started chatting with her, and wound up caught between loyalty to his roommate (his best friend) and the pain of someone he liked who was asking him questions she felt she had a right to know.
What actually happened, the timeline, in the poster’s words
According to the OP, his roommate and the girl he’d been seeing broke up in early January and had been “seeing each other on and off.” The OP bumped into the ex and they sat down to talk. She asked whether the roommate had been seeing anyone recently. The OP says he knew the roommate “has been seeing other girls” and told her some of what he knew, intentionally vague but honest enough to make her upset: he mentioned that the roommate might have hung out with someone in late February and that he’s been seeing “this new girl and others this whole time.”
Hearing that, the ex “breaks down crying” and immediately confronts the roommate. Later the roommate calls the OP and asks if he’d said anything. The OP says he was planning to tell him, but that same night he ran into the ex again while walking with a friend. She begged him not to tell the roommate, saying it would break his heart to learn his best friend had “told on his ex.” The OP agreed to keep quiet. The roommate then finds out by some other means, confronts the OP, calls him a “snake,” and accuses him of trying to take his ex. The OP posted asking whether he “ed up” and if he can recover the friendship.
Why this felt so messy to everyone involved
This situation triggers several kinds of hurt at once. The ex feels betrayed and blindsided, she asked the OP directly and was given news that crushed her. The roommate feels betrayed by a friend who he believes should have his back; he sees the OP’s silence as a deliberate choice to protect the ex and possibly to position himself in the romantic drama. The OP is left stuck between two requests: the ex asking for truth and secrecy, and the roommate expecting loyalty and discretion. It’s easy to see why emotions escalated.
Reddit responses split down the middle. Some commenters defended the OP as doing the right thing by not covering for a friend who was seeing multiple women, while others accused him of dishonesty for lying to his best friend when asked directly. One top comment by u/Dr_heal_with_fire called it “ESH,” noting “You say you’re a honest person but when it came to him you lied,” and also criticized the roommate for his behavior and the ex for using the information to confront him. Other voices were clearer: u/Street-Step2028 said “NTA. You saved that girl from wasting her time and love,” while u/lauraz0919 pointed out that the roommate’s secrecy looked like intentional deception and that the OP shouldn’t be forced into covering it up.
Was bro code broken, and who’s really at fault?
“Bro code” is shorthand for loyalty between close friends, but it’s not a legal rule and it doesn’t erase other moral responsibilities. If your friend is intentionally hiding romantic behavior that affects other people, some argue you have an ethical duty to be honest with anyone who might be hurt. Others argue that once your friend directly asks you to keep quiet, you owe him honesty rather than silence. The OP did both: he told the ex about the roommate’s behaviors and later lied by omission when the roommate asked if he’d said anything.
That dual action, telling one person and denying it to another, is what most people find unforgivable. Even sympathetic commenters who thought the OP protected someone vulnerable still flagged the dishonesty as the real problem. As u/Exotic-Rooster4427 said, it “depends” on whether the OP found his friend’s behavior acceptable; but many agreed the friend’s stringing others along was unfair, and that having this information isn’t the same as choosing to weaponize it.
How to try to repair the damage (practical steps)
If you’re the OP or anyone in this position, the immediate repair starts with owning your choices clearly and without excuses. Don’t soften the timeline or blame the ex for asking you not to tell the friend. Be direct: explain what you were asked, what you told, why the ex was upset, and why you made the choice to keep quiet when asked. An apology that acknowledges both the hurt and the specific breach of trust matters more than explanations about being sympathetic to someone who was crying.
Offer to make amends in concrete ways: let your friend ask questions and be ready to answer honestly, volunteer to be present during difficult conversations if that would help, and accept whatever boundaries he sets after. Don’t expect trust to be restored overnight, it will take consistent honesty over time. If your roommate continues to behave deceitfully in his relationships, you can explain why you won’t be his cover in the future and be prepared for that to change the friendship dynamic.
What To Take From This
There’s a difference between loyalty and complicity. If someone is actively deceiving multiple partners, staying silent isn’t neutral, it enables more hurt. But protecting someone’s feelings by lying to their face is typically worse for trust than telling an uncomfortable truth. The OP’s critical misstep wasn’t that he told the ex the roommate was seeing others; it was that he lied when his friend asked him directly. That’s what made him a “snake” in his friend’s eyes.
Going forward, pick your side before you’re pulled into the middle. If your loyalty is to your friend, tell them the truth and give them the choice to handle it. If your loyalty is to fairness and potential victims of dishonesty, be transparent about that and accept the consequences with your friend. In messy relationship drama, honesty is messy too, but it’s usually the only thing that lets trust be rebuilt instead of shredded.
