What happens if my boyfriend calls me a *****?

So, me and my boyfriend have been dating for about a year now and I love him. I really do. He was at my house one time and we were just cuddling on the couch like any normal couple. Then out of nowhere he started insulting my best friend. My best friend's a guy, so I get that he can get jealous at times but what he said kind of struck a nerve in me. I started yelling at him. We yelled at each other back and forth and at one point I got so frustrated that I slapped him across the face. It got all quiet and we just stared at each other. Then, out of nowhere he just said: "Call me when you're ready not to be a psychotic *****." And then he left. It really stung when he said it and I cried myself to sleep that night. We're still not talking and I just wanna know where this is going. Does it mean anything? Is he gonna break up with me? Guys call me a ***** all the time. But just for fun. When he said it though, it actually really hurt. I still love him though. I love him more then anything.
