Am I Wrong Here?

So I am 22 weeks pregnant and I feel like I have literally no support from my boyfriend. He's been over his sister's almost everyday for the past week and a half. Me and her actually got pregnant around the same time and were just a few days apart on due dates. Sadly two weeks ago her boyfriend beat her so bad she lost the baby and he almost killed her. She looks rough. Her arm is broken. Half her teeth are knocked out so her voice has completely changed. Since both their parents are useless bastards, he's been over there taking care of her, or he'll bring her over here. It may sound selfish but I don't feel like I'm getting any attention. She's very self conscious about her face. Especially since half her teeth are gone and he says she's still beautiful, but here I am getting fatter and fatter and don't feel beautiful. I'm caring his child. He's supposed to make me feel like a warrior, but he doesn't.. What should I do.
