Should you tell someone if you know they have been cheated on?

Answer 1

This is a really sensitive area and you really have to weigh the pros and cons but ultimately honesty is the best policy. If you do tell someone such a thing you had better be prepared to back it up as well as the possibility of losing any friendships you may have with these people.

EDIT SaraFV:

Well, I had a simular experience with my friend whose boyfriend wasn't cheating, but did flirt with other women and continued to participate in PUA (Pick Up Artist) activities. I didn't feel right about her not knowing. (My boyfriend did the same, but he told me about it and I'm okay with it, because it doesn't go any further than that.) So I told her. She was upset he kept that secret from her, but he was also upset that I didn't go talk to him first.

I thought: "Dude, she's my friend and I can talk to her if I want to." But then he pointed out that I could have told him that I knew about it and that I wanted her to know too, so either he'd tell her or I would. Which would give him the opportunity to talk to her himself. (Which is always better than finding out through your friend.)

I never thought of it that way and I do feel that he has a point. So maybe that's worth considering if you find yourself in a simular situation. Perhaps it's better to talk to the cheater first. (Perhaps you need to collect evidence before talking to him, because if he's really just a jerk and doesn't feel remorse, then you should be able to talk to your friend before you three end up in a fight over who's right and who's lying.) And follow up on them to make sure he actually talked to her.
