One friend(20,F) of mine(21,F)(whom I considered my best friend, call her S) went through a breakup after her bf(20,M)(say X) cheated on her. And boys in our class believed her bf's story that she broke up with him because she wanted to date someone else.Her ex started drinking and taking drugs and used to pass out most of the time.And the boys blamed her for his bad condition. One of them said "if I was X, I would have paid boys to gang rape her". My then friend(20,M) (now bf), call him G, told me about this and said not to tell her as she would get hurt or anyone else. He said that if everyone (the boys) got to know that he was spilling the boy's personal conversations, they would hate him. But I didn't think, anyone would actually do that, and I told her what the guys were saying about her. She eventually complained about this to our college authorities, where G acted as witness supporting her claims. And the boys started hating G, removing him from all groups. They went to the extreme of giving him death threats. Not a single guy would talk to him, they made his life in college miserable. Now he has no friends (except me) and a lot of enemies who make his life tough in every aspect possible. Even 'S' and her friends would bitch about him saying that he took a stand for her(S) only to impress me, even though they know the severity of the situation G's in after all this. Am I the asshole to tell her that? I betrayed G's trust.
