When is enough enough ...

So past couple weeks I have not been getting any sleep due to baby up. (9mo.) My boyfriend has been getting off of work goes to gym like 3 hours then plays PS5 another 2-3 hrs and goes to bed late. His 6yr daughter from previous relationship has been here for week and they even sleep on couch. I'm at the end of my rope asking for help or giving me some space or time to myself. I watch his daughter during day also. The thing is my blood pressure has been high past month and I today was extremely high and I went to urgent care. They did an EKG on me and prescribed me BP pills and some to help sleep. I let him know and he even blames me that I get worked up over nothing. I asked him to stay home after work so I can go to bed early and says no he has to have that time. Even if he could take a couple days off yo help get my BP back to normal still said he can't. I said look what your acting and you don't even care. Not even concerned about my health. He says im selfish, and never help with anything . I got layed off from covid and had baby so yes its been alot. I stay home and watch 5 kids , cook, clean , laundry , buy most of groceries pay electric gas any household items, all babys needs car payment as well. I'm receiving unemployment and have my tax return so I do help contribute but still says I do nothing. I'm so close to leaving but have no where to go and no job since he told me would be ok for me to stay home. He came home at 11pm & not once came to my room to see if I'm ok. All I'm asking for is prayers cause I'm so scared I'm gonna have a heart attack with all the hurtful words he says and so much I'm taking on. I'm hard headed too and speak up I do not let him talk to me like that so we get to arguing. Please if I can just receive prayers and kind words or any suggestions 🙏would help.
