Issue with Fiancé

Every time I bring up a concern of any kind my fiancé starts flipping out… screaming, yelling slamming doors, cussing, calling me all kinds of dumb and stupid and says I like drama and starting fights.

We argue sooo much and it always ends in aggression and he blames me. Says I make him react the way that he does. Either I talk about my feelings at the wrong time or he feel like I’m being smart… either way all of his blow up’s are my fault apparently. I told him I was done with the relationship and I wanted him to leave and he flipped out even more. He stood over me screaming while our 3 month old cried and screamed as well. He says he’s not going anywhere. I want to call the cops so bad but I don’t want to get him in trouble, plus I know he doesn’t have anywhere to go (I basically take care of him) but I honestly can’t stand to be around him. Not sure what to do at this point…
