Boyfriend problems, advice pls?😭😭

My boyfriend belittles me a lot, calls me stupid, lazy, a shitty mom, etc. I’m 15 weeks pregnant with baby #2 and I’m so stressed. We have a lot going on and all he cares about is video games. I’m applying for job for him since he quit, and he bitches at me for not having a job, tell me I don’t do anything even though I do, makes me feel like a complete failure even though I’m putting my education on hold for us. (He yells at me about school sigh) I’ve cleaned, cooked, done his laundry, take care of him and my son, try figuring our situation out, apply for jobs for both of us. I’m stressed to the max and haven’t showered in like 2-3 weeks, I eat 1-2 meals a day.. I don’t take good care of myself anymore. my mental health is crap again and I’ve been noticing I’m becoming super depressed again. I feel so alone in this all. I’ve tried talking to him like adults but nothing works, it always end in screaming at each other. I have bad anger problems, and I’ve been handling them much better since I got pregnant with my son (2 1/2 years ago). He knows this, he knows my past and I’ve explained to him what used to happen when I got angry. He keeps trying to bring that part of me out for some reason. I just don’t know what to do, I’m so lost. I’m alone in the pregnancy, and I’ve talked to him and told him I need his emotional support but be doesn’t care. He doesn’t show me affection anymore, I don’t even know if I wanna be with him anymore because of it. This relationship is stressing me out to the max.. 😭

Update; Where would I even go? I have no one. I’m getting kicked out in 2 weeks, we’re going to his parents. I have no family. My moms near me, but I don’t want a meth head around my kids. I just turned 18, my credit is shit because of my mom. I’m looking for a job, I literally have no one but him and his family right now. I’ll be homeless. I want to leave him, but right now I can’t.. I won’t even be able to take care of my son.😭😭😭😭
