Marriage and pregnant 38 weeks

Really starting to think that getting married to him was a mistake considering after even 6 months it was funny I flinch called a whore from past issues and doesn't seem to matter to try anymore and I'm already to the point I don't want to be here anymore I try to be a step mother and when I do you get pissy when but when i dont and stop you get pissy because im not trying but yet i cant try when you dont let me unless you dont want to try with your own daughter-.-
