Baby daddy

Me and my baby daddy use to date and then we broke up but we was still sleeping together and then i got pregnant. I am 10 weeks pregnant and we had sex last week and this week he says he doesnt want to have sex with me anymore and i asked him if he is having sex with someone new and he says no. Today i was suppose to talk to him and he says leave it for tomorrow and he said he is with someone right now and i asked him if that is his girlfriend and he said i never said it was and i said are you fucking her and he goes keep assuming. I want to be with him again but he doesnt like me like that. What should i do ?
