I need advice

First and foremost I am here for advice not to be talked down to or to be judged so if you’re here for that please don’t bother.

My husband and I have been having many difficulties these last couple of months. I am 12 weeks pregnant, we’ve had 3 miscarriages before back to back. That’s something that definitely took a toll on us. We have been arguing a lot, it’s usually over the same thing all the time. He has a major respect problem and has no house manners, well manners at all. He can be very immature, all he talks about is guns, fights, shootings. All the above. He knows how I feel about guns because we had a situation not that long ago he had the gun in the car and he was playing with it like a child and the gun went off and he put a hole into my glove compartment. It was an accident but I made it very clear he’s obviously too immature to handle a gun, I understand if he wants a gun for protection or whatever but it should go in a safe and only should be taken out if needed or if going to the range. I think that’s reasonable. Well for the last month he’s been looking into buying a gun and it has me on edge. Next, we left our apartment because want to save for a bigger place and my step son wants to come with us and a baby is coming. So we came to his moms house.. his mom is a hoarder honestly she is really dirty. I have OCD, so it drives me crazy tbh it gets me in a really shitty mood all day just being around the mess but no matter how much I try to clean around and organize it doesn’t last. That’s the way they like to live. I get it, it’s not my house but I’m not in peace. We have two dogs one is mine and one is his but I take care of both of them. His dog is extremely aggressive, he can only be trusted around me and my husband no one else. Lately he’s been attacking my dog, which pisses me off because my dog is so sweet and innocent he’s a good boy but my husband refuses to do something about him. Tbh I don’t think he should have a say since I am the one who takes care of them. More, the respect thing. He does not have a respectful bone is his body, he is constantly talking about the girls he’s been with in the past, talking about the dirt he’s done in the past. Don’t get me wrong it’s okay to talk about your past here and there but it’s all the time mixed with everything else the violence, the guns and all that. He knows I don’t like it, and I tell him to simply just not talk about it in front of me but he chooses to literally rub it in my face and I’ll say can you just stop please and he laughs and just keeps on. It’s gotten to the point that I can’t stand him. He’s constantly threatening me, constantly calling me out my name is I say something he doesn’t like then he says if I don’t like it to leave but if I try to leave he has a fit and he scares me I’m ngl. He gets crazy... threatens to take my baby, threatens to hurt me. He is controlling. I can’t go to my friends house to do my nails, I can’t talk to my mom(we have a strained relationship) but I want to fix things with her and I’m not saying I want us to be best friends or super close but I do want to have a relationship with my mother at some point. He says the day I decide the speak to her it’s over. That he loves me but he doesn’t want anything to do with her. I say he doesn’t have to have anything with her but he can just support me but no, that’s not the case. I can’t do anything, I can’t get the job I want because what if other guys work there ? Men are all over the world I don’t see the issue if I work with some men, it’s bound to happen anywhere I work or go! I don’t know what to do. I dontknow if it’s the pregnancy but I literally cannot stand him anymore, he annoys me, I cannot take the disrespect anymore, I cannot take the controlling and manipulating. All we do is fight and disrespect each other and I don’t want the be in that environments and I don’t want our child to grow up around that. He’s always complaining saying I always have an attitude and I’m always mad. How am I not going to be? Who wouldn’t be mad all the time living like this everyday. The truth is I don’t know where I would go or who I would turn to because I’ve lost everyone and everything because of him. I have no money saved up, I have no friends, I have nothing. I don’t know...
