Frustrated with partner

My partner and I just moved into a house and I'm 29 weeks pregnant. He keeps saying he needs to relax (drink/smoke) while he can before baby and pushing everything on me when I'm exhausted. There is work we need to do on the house and he either flat out refuses to help or complains and half finishes stuff. Whenever I just do it myself he gets on me about overdoing it and then says I didn't do it right. This isn't just one thing he always finds something negative to say. I'm so sick of it. If I'm already going to do everything I'm at the point where I'm considering if I need the bs and drama. Tired of fighting and never being listened to. He says I knew who he was and he doesn't want to change. Maybe it's time to grow by myself? Don't want to make rash hormonal decisions though. I don't have family and really need his support especially now, but even saying this doesn't make him see where I'm coming from.
