My roomate's boyfriend does not respect women?

I live with my roomate and her boyfriend, and her boyfriend Sal does not respect women at all. He would always compare my to my roomate Kyle (I know, it's a boy's name), saying that I have small t!ts, and that hers are bigger than mine, asking us if our pubes match our hair color, never wants us shaving our pubes, cause he doesn't understand why everyone shaves down there, every time we would both be talking, and Sal would come into the room, he'll always say things like how it smells like fishies in the room, would always comment on women on every tv, like oh she has a hot @ss, or she looks like a prostitute, he also hits us when he gets mad, like whenever Kyle and Sal get to an arguement, it always ends with Sal grabbing her hair and yanking it hard, beating her face in, and hitting her with his shoe, and her crying, one time, I forgot to buy him coffee after I came from work and he flipped out and pulled my hair all knocking me to the ground, and started cursing at me, he always calls us stupid b!tches, calling me spoiled, criticizes about what we wear, he thinks everything we wear is stripper clothing, especially skirts or dresses, like he'll always lift up our skirts to make sure were wearing underwear, and we both never got outside on public without panties, so I don't know what's his problem, would curse at us everytime we forgot to clean up something, I really don't want to deal with Sal anymore and I want him gone, but Kyle really loves him and doesn't want to leave him, despite that he's abusive to her, so I'm afraid if I kick him out, she might not like me anymore, so what should I do?
