One sided marriage

It's been going on awhile were he doesn't even want to physically touch me sexually but now..it escalated to even just hugging and he physically pushed me away and told me to go away. I just walked away and I died inside. But he doesn't see that side of me. The part where he kills me because I feel as if its my fault for being pregnant and fat. It's my fault because I'm always working or at school...it's my fault because I can't be the perfect wife he wants...I honestly just want to have a two sided marriage when he felt the love for me back... rant over...
