Need some advice

So I am 31 weeks pregnant. My boyfriend and I have been dating to years. The pregnancy was never planned. When we found out he wasn’t to thrilled. Now we both don’t have any jobs he has no motivation. And he just recently got in a car accident. And got a concussion. Then he borrowed money form his mother and then went to the liquor store and gave the rest to just a random guy. We have a 4 month old big breed pup that I no longer feel safe walking due to what could happen because he is a very strong dog. He still refuses to help and say that it’s my turn and I need to walk him too. I just feel he has no sympathy for me being pregnant or wanting to help in any way. He also told me that I’m forcing it down his neck to accept it. Which I think he should by now. I mean I only have two months left. I said he could accept it or leave. I’m at the point where I feel it’s right to leave him but I never pictured myself having a child without the dad. Just not sure what to do...
