Someone Please help me Im begging you, i need some advice Im so cofused?

Well, i have a problem his gf called my phone an left me a nasty message, so I called him back telling him I did not aprreciate that. She basically said dont call him an he wont be calling you an whatever you do at school I dont care an then she called me a nast ***** an said stay out his face. So I asked him, oh so you dont wanna tak to me no more an he said to me " Did I say that? I said no, so he said ok then I'll talk to you later. I have not heard from him this whole weekend, I mean at first it bothered me but I really dont care if he nevers talk to me, but the thing is he is in my cl, so should I ignore him or what? I mean he was the one who started to hit on me, She saw a text message I sen him saying I think we should just be friends an not go any further, b/c he has a girl , but I do care about him. So I mean there is no reason 4 her to get mad is there, she should be happy I put him in his place right? Im so confused, what to do? I mean I tried to do the right thing
