If a good friend of mine did something more severe, in this situation make out with my ex regardless of the talk we had before and him saying that she's this and that. It came out more as a betrayal from my friend that he'd do something like that. I don't really give a shit that they did what they did, I was only annoyed by my friend's hypocritical act.

I brought it up yesterday with him and we talked about it a bit. Now I'm not sure if I should've just started talking less and less with him because of his actions or address it with him and give him a second chance.

He said he did it because of some other drama I wasn't involved with and he thought we were going to stop talking to each other.
