What would you do

So everyday for the last year with my boyfriend of 8 years has been the same, I’m 7 months pregnant now, he goes out early morning not back till late at night and goes to his moms from work or his friends, even on weekends and not one phone call throughout the day or text, I’m pregnant he talks to me like shit and treats me like shit, I can’t take no more, he’s told me basically that I’m white trash, what should I do when he comes back later tonight, should I tell him it’s over and to leave me alone? He won’t care that I say it’s over anyway, he really doesn’t care
