Should I leave once and for all? Or am I overreacting? Please help me

Well my Bf pays me no attention and I just really feel I’m being foolish . Every day off he gets he leaves . Are you ladies used to that ? I just wanted to talk to him about all I was bothered about Bc he never addresses it or speaks to me about it. Today he wanted to watch the game and sleep but I wanted to converse about the problems we had going on that had been persisting for days .. bills , our kids expenses etc.. he just continuously ignored my questions while I’m sitting right in front of him.

He sat there on the phone and played angry bird like a kid and he’s 29. I also got him the phone and I feel dumb Bc he barely contacts me and ignores me when it comes to serious questions . I’m just stressed to the max Bc I’m about to deliver in less than 2 weeks and we’re having problems with our second grader and her behavior. I feel he’s really not here for me and I just don’t know what to do Bc he’s the sole provider .

I asked him could he help me clean up my room Bc I can barely bend down and I was cleaning up the rest of the house Bc our lights had been off and it was needing a little tlc. He made a threat to leave as if I needed him there . He acts like he can’t even converse with me but he will sure out his shoes on and leave with my phone . I just feel dumb .

Sometimes I have cut his phone off I won’t lie , but I know I can’t control him or use it against him. Just makes me feel dumb as heck how’s he’s treating me and I can’t do much until after I deliver .. I can’t reach out to him and really feels he doesn’t care and he always says I’m tripping but his actions say a lot more .. I’m so alone and I’m just fed up to the max with everything. He also hasn’t got anything for our baby and it just hurts ... I just need to find a job and get on my own , I just know it’s gonna be hard...
