Open liquor in car

Sooooo I’m pregnant almost 7 months and I already have a child. The child that I’m carrying his father and I have not got along for a while now. I typically don’t put up with people bullshit but I’m pregnant so I’m trying to but I’ve been unhappy for so long and I just feel like I’m alone emotionally, financially and just in general. We don’t talk or tell each other our problems he says that if I can’t help him with something why should I tell him. Mind you we have a baby on the way. So last Saturday he asks me to come sleep over and stuff so I said okay. I bought ice cream and cinnamon rolls for the morning. I get there he’s drinking a beer which I didn’t mind but he was kinda being cocky and ignorant towards me which I didn’t say anything but it was a turn off. He kept saying he was hungry so I said I would go get him something because all he ever said is he doesn’t have money for food. But he didn’t want to so I went and sat on the porch steps because it was hot on the porch. So we get in his car to go get food and I saw a empty glass beer bottle in the cup holder and then I saw a glass beer bottle in his hand that was maybe 30% full. He had open liquor in the car with me while I’m carrying his child and he sees nothing wrong with it. He’s done this years ago and I’ve asked him not too. So I got emotional and started crying then we were sitting in the car and he’s still sitting there not talking being ignorant because “he worked all day and he’s tired and he’s hungry” then I kept begging him to communicate with me and he didn’t want to. He says I’m a spoiled brat because my parents helped me get a house like the house is in my name and my fathers name my dad helped me get it for me and the kids. And he’s the only person that makes me feel bad about the house me and my dad got. So I told him go find someone that’s up to your standards that you can live in the ghetto with because that’s clearly what he’s looking for by the way he acts. So he yelled at me “get the fuck outta here” like 5 times and I was kinda like wtf then he gets out of the car and walks off because he has some anger issue that I don’t feel like dealing with. So I got in my car and drive home and he called me I kid you not 30 times and I wouldn’t answer so he showed up at my house expecting to fix it with me. He made me so upset I haven’t felt that upset or cried thar hard in such a long time. I work I provide for my son and this new baby I’ve bought everything for him. All he bought was a box of diapers. I just want out so bad and I know it seems so easy but it’s not and I try to hard but keep going back because of the baby can someone please help me.
