My bf? Fuckbuddy?

Ok so I have been talking to this guy for a couple months and I really really like him. But we aren't dating and everytime I ask what we are he says idk or that we are talking. And this past weekend I was so upset because everyone was telling me shit because I already had sex with him. And so I went to a kickback and drank way to much. I got blackout drunk. And I found out I had sex with another guy. And he knows and we talked about it last night but he said that he was expecting it and he didn't care but he made a huge deal about it. And he said that he's fine with it but he doesn't want to hear me ask "why aren't we dating?" Anymore. But I don't know what to do. I like him so much but he calls me a hoe sometimes and I don't know. What should I do?
