Relationship ending

Hi ladies I need some encouragement.

I’m honestly starting to feel like my relationship with my partner is coming to an end. We have been having problems recently and I don’t see us coming to any middle ground anytime soon. It all started with back in October he was laid off from the place we were both working and I was having problems there so he told me that if I didn’t quit we were op up( I was 12 weeks pregnant. So I left and have stayed home since due to pregnancy and caring for the baby. Now I hate staying home and I’ve always told him that but I agreed to stay home until September and then I was going back to work. Now that it’s drawing closer we have had more and more arguments about everything. I feel like he does nothing for himself. He works long hours (6 am to 6 pm) and I understand that, but he does nothing else. I care for both our kids all day, cook, clean, grocery shop, etc. He doesn’t even pick up his own clothes or make his own plate. He thinks I should drop everything to do things for him and I’m starting to hate it. I breastfeed our son so that we don’t have to pay for formula but all he ever says is I’m “spoiling” the baby and gets mad when the baby wakes up to eat in the middle of the night. He’s always comparing our kids to his and his ex wife’s kids. He calls his “sister” everyday and they’re on the phone for hours. He doesn’t even come in our house until like 9 pm every night. And he went from occasionally drinking to drinking all the time. I just can’t take it anymore.
