Annoying boyfriend 😡

Kind of just need to rant and need a bit of advice. Im 33 weeks pregnant and been arguing with my partner quite a lot. He seems to think he’s now ‘strapped down’ and hes just ‘not that kind of person’ so doesn’t think we will work. I don’t work, suffer with severe mental health issues and have been alone all this pregnancy. He works, goes to the gym two nights a week and boxing one night and spends one day of the weekend with his friends. I see him on Saturday and that’s about it if I’m lucky as every other night he’s playing fifa! He says I’m tying him down and he’s not happy but am I in the wrong for thinking he’s just being a selfish bas****?? It was his idea to get pregnant in the first place so not something that just happened. She’s coming soon and he never wants to come shopping for her or do anything to her room and it’s leaving me in a bit of a lurch about what to do. My Mum has offered that I move in there but I just don’t know what to do this late on. :(
