Is NOBODY wrong in the post ? POST : Backstory to this, my girlfriend of two years broke up with me, and in the beginning the only explanation she gave me was that we just drifted apart, and that alone would be completely fine. I didn't accept that answer, and after asking around it turned out that she in fact liked someone else at the same time, and had started dating him less than a month after we broke up. After confronting her about why she lied when breaking up with me, she told me it had only been a "facter," and she only started liking him after we broke up, and the main really was that she just stopped loving me. I accepted that answer and moved on.

So a couple months go by, and today while talking to a friend about her he tells me that the entire reason she broke up with me was because of the other guy, and she lied to me about pretty much everything else about why she broke up with me. Would I be the asshole to reveal to her friend how much she didn't like him and shit talked him? This wouldn't be much of a big deal but she frequently hangs out with him and acts really friendly, but in reality she completely dislikes him and everything that he does. Would I be the asshole if I did this?
