I am extremely stressed out

I broke up with my bf/bd because I’m tired of feeling like a single mom in our relationship. I am currently pregnant with our second child which is due in 2 months and he’s not making any effort to work harder or find a better paying job. I will not be getting paid maternity leave and I’ve been saying this for months hoping that it will click. He told me that he doesn’t recall me saying this and he feels like we should be fine if we are behind on a few bills. He only brings home 400-500 every two weeks. My income pays majority of the bills and I’m trying to get as much overtime as I can before baby boy gets here but I’m literally exhausted and tired. He wants to be in a relationship with me but when I tell him what that requires & im not settling being with him anymore he gets mad. He says that he can DoorDash while I’m out for 6 weeks. Part of me just wants to do 2 or 3 weeks and return back to work because I hate being late on my bills and having to play catch up. I’m buying everything for baby boy while he just sits around playing video games. I really want to kick his butt out of my house and my life but I’m afraid of doing this all by myself and having to find a baby sitter for our kids when I’m trying to make ends meet as it is.
