A stressed out mom

Being a mother is so freaking hard and very over whelming. I’m 24 and 3 year old and 5 year old. My 3 year old’s father and I are still together. We live in separate houses and we plan on moving in together. But I’m having doubts I feel like he doesn’t help enough I don’t expect him to do anything for the 5 year old because it’s not his child. But I feel like he can take the 3 year old more than he does. I have been out of work for a month due to my daycare shutting down. I was blessed enough to find a job where I can work from home, so if the daycare closes it won’t be a big deal for me. But my boyfriend always says he tired from working but what about me. I’m tired of chasing two kids around the house all day cleaning cooking. When I had to commute back and forth to work I had to fight with two kids to get dressed every morning, even to do something simple like grocery shopping. I have no peace I can’t never take a long thoughtful shower or even use the bathroom in peace without a child knocking on the door or busting in on me. Like wtf, I don’t even care about going out with friends all I want is sleep and peace. Every time I ask him can the baby spend the night with him it’s oh I have to get my room straightened out or I’ll take her next weekend when I’m off but it never happens. And I’m fed up with it idk what else to do I talked to him. He always brushes it off I cry every single day from being frustrated overwhelmed. Then he tells me that when we move in he wants another child I don’t want anymore kids at all. It’s too much on me, I know I can’t deal with it. I tell him this and he gets mad. Idk if his mom doesn’t want the baby there or something idk or understand why what’s the issue. I feel like if you can’t take her when I need a break there is no point of being in a relationship. Yes, he buys her stuff and he also pays child support but raising a child is more than money. You really have to be there for the child. I feel like I shouldn’t have to keep turning down jobs cause of a baby sitter or putting my life on hold. Like when can I actually start living. What should I do?
