A very hurtful foul-mouthed boyfriend during fights?

When me and my guy fight, it gets real bad. While we both provoke each other more and more, he bites where it hurts(not literally!). He can get really nasty with his words and wouldn’t stop although he knows he is hurting me. He is rarely guilty of his actions. I don’t expect an apology most of the time, I just want him to back off and let things cool down naturally but he can’t even do that. He says the name-calling and rudeness is only because of the temper and he doesn’t mean them but they hurt real bad. He has a problem with my past and has called me a s***, when in reality, his past has been 10 times worse.

How do I make him realize his hypocrisy and make him respect me? I don’t give up on relationships easily, I have only had committed partners in the past but is this a lost cause?
