I'm having problems with my boyfriend, I need help?

Okay we were laying in the bed getting ready to go to sleep and I got really cooled and I wanted to sleep at the wall and he said something really disrespectful to me. This is my problem... I said, "Baby can we Switch places cause I'm cold and I want to sleep at the wall". And what comes out of his mouth is this "I will let you get the wall if you give me some h.e.a.d. I started to cry and then he said I'm sorry baby I was playing but he has never talked to me like that. And on top of that I do everything, I work 80 hours I come home and I cook, clean, wash, and we have sex and everything in between like every single day. And all I ask is that when is not working to cook or clean up be does he know. So Thursday was my only day off, and I didn't everything he wanted and needed. And when I ask for one little thing he becomes rude with me for no reason. And not to mention I pregnant with his child and he disrespects me like that. What should I do?
