Help!! please!!

Okay so I've been dating this guy for over a year. Before we got together he was so nice and sweet but then when we started dating things started to change. He made me get rid of my guy best friend who I knew for years but he's allowed to keep his girl best friend because he's known he for all of his life. I don't think that's fair at all. I'm not aloud to talk to guys at all and if a guy even steps into my line of sight he will get mad at me and say that I was checking them out. I can't leave the apartment on my own because he doesn't trust me so I don't have a job or anything. And since I don't have a job then I have to clean the apartment every single day. Well I'm pregnant and it's been taking a toll on me because I'm really tired and get really out of breath at times. I'm not aloud to take naps though. And I have to wake up in the morning when my boyfriend wakes up or else he will make me feel like shit about me getting to sleep in when he can't. And also whenever we are out I can only wear clothes he allows which is usually jeans and a tshirt. Well my jeans are getting too small since I'm pregnant so be really been wanting to wear my yoga pants but if I do then my boyfriend will just say that I'm showing off my body. And this morning he made me cry because I forgot to put the laundry in the dryer and he didn't have a sweatshirt to wear. I'm scared that if I leave then he will try and hurt himself but I really don't want that to happen because I really do love him more than anything. Just somebody please tell me what to do.
