"Can't have sex with me"

I'm going to be strait up my pussy literally aches for my boyfriend but he "cant have sex with me". We broke up about a year ago for 6 months and in that time I had slept with someone else and now he "can't fuck me the same" so he really just doesn't at all. Once a month maybe although we usually go longer.. especially lately and since I've been pregnant (4 months) we've had sex TWICE. When we do finally do it it isn't even good for me and I can tell he isn't even into it. There's no foreplay involved just stick it in he cums and done. He watches porn but won't have sex with me and i want it so bad but I can't keep complaining to him about it because he says the same thing and gets mad. The other day he said "your pregnant why are you worried about sex". I want to cry😩 i love sex and I love it with him. I can't live without him but I can't live my whole life without sex either wtf do I dooooo😭😭😭😭😩
