I don’t know what to do! Abusive husband.

My husband had become extremely abusive lately. He’s under a lot of stress but it doesn’t justify his behavior. He calls me names, puts me down, calls me a fing bitch, a c*nt, retarded, stupid, incompetent. I get screamed at and put down the first few minutes I wake up and before I go to bed. I feel terrorized by him. I ask him to treat me with more respect but he says I have to earn it. He said I’m a horrible person with no good qualities and that I’m vile. I want to leave sooooooooo bad but I’m pregnant with A very complicated pregnancy and have to go in every day or every other day for doctors for next month. Then planning to fly home with my family. He doest contribute to any baby costs because he says he pays my utility bills which he expects a refund on. He never apologizes or acknowledges his behavior. He doesn’t think he’s abusive. he says well then don’t be x,y,z. Yesterday he spit at me. I was so shocked. My birthday is on Christmas and I just want to be left alone and have peace. He won’t leave! I’ve asked him to go to his family but he won’t. I’m besides myself. What do I do?
