Lost

I have been in a serious relationship with my boyfriend for a little under 4 years. Its been a long roller coaster ride, filled with many ups and downs, I like to say we are in a hate/love relationship. We have been living together for about 2 years. I feel like we are only getting further and futher apart, mainly because of his temper. He has a tendency to over react over little things in life that you have no control over, like traffic, and when I state the facts and tell him its never going to change and always been there he turns on me and starts calling me hurt-ful names like "slut" "whore" "bitch". Its like that whenever we fight and he always suggest breaking up and then putting all blame on me, like we are only fighting because I started it. Like hes King Perfect and we should all bow down to him. However mad I get I still have strong feelings towards him and I find myself at this crossroad. To break up and find someone who respects and cares for me ..... or to stay in hopes that he will change and things will work out how we always talked about.
