Advice on Baby dad??

I went to hangout with a friend last night and was supposed to stay when I got done, but he fell asleep why I was waiting on a friend to bring me Zantac so I'd be able to sleep without heartburn. He fell asleep and I called him 3 or 4 times before I went home, in hopes of waking him up but didn't. This is what I just woke up too. No matter what happens I'm the bad guy. Always. He constantly makes me feel like I'm doing something wrong when we fight and always leaves every time and is trying to apologize and come back the next day. It's been almost a year and I'm so lost. I'm due in September and he hasn't so much as bought our daughter one single outfit. I'm so lost at what I should do. I don't think he deserves to have his last name given to my daughter but I don't want to cause further problems. He's made me leave friends behind and stop talking to people who I've never had anything to do with sexually or intimately at all. He can be so sweet and loving but turns around and does this. I'm at a loss for words or what to do. Someone help? What should I do? Does anyone else think he's over reacting about this? I'm also 26 weeks with his baby
