Christian boyfriend keeps pushing sex on me

Anon

I am a Christian. So if my boyfriend. He is more of a devote bible pusher and I am more spiritual but either way we both go to church and Sunday school together and pray together. We are not married so I don't want to engage in sex (although I have in the past). He really wants to have sex anyway but I don't and I tell him that all the time. Last night while I was sleeping he pushed my panties to the side and tried to put his or is inside me. I turned over and he was completely naked. I was wearing a pajama shirt, underwear, and shorts. I feel like he totally disrespected my body and God himself. We has JUST prayed that night b4 bed and only 4 hrs into sleeping he pulls that stunt. I'm so upset that I don't even want to go back home. I left the house. My house. He is living with me for finical reasons and because he doesn't like his own family and we are both grad students. I talk to him all the time, we read scripture, we pray, but AGAIN he always tries to have sex with me unwanted or tries to convince me to have sex. What do I do?
