Boyfriend trouble. Need support

My boyfriend and I ( been together 10 rocky years) got into a fight yesterday and he said some mean things to me. I'm usually a very passive person but for some reason yesterday I was feeling brave and told him if he says those things to me again he can move out and that I'm not going to be put up with name calling. Of course I don't want him to leave but I thought it might make him understand hurtful the things he says are. Well since then he will only give me yes or no answers he won't look at me or even be in the same room as me. I'm sitting in my bedroom crying and feeling like crap about myself because I just want us to get along and he's in the other room acting  un fazed by everything. I feel he's the one who should feel bad and not me. He has a way of turning every situation into being my fault some how with out really having to say much. I don't know if he's upset that I stood up to him(something he's not use to) or if he's actually contemplating leaving. Sorry for the rambling I just needed to get that off my chest.
