Divorce, stress, and trying to rebuild while pregnant

My husband and I are getting a divorce. It's been a rough pregnancy and I'm currently 32 weeks. I've been stressing since I got married to my husband. We got pregnant shortly after we got married in September and after he got into a car accident in December we were jumping from place to place trying to live. My husband was the first man that I was ever with sexually, the first that I ever dated. His family was initially warm and welcoming after finding out I was pregnant. It slowly melted as I lived with them, I was talked about, argued with, yelled at, harrased, etc...I endured all because I thought that he loved me. I didn't even think about my child or the state I was in mentally. My parents, my ENTIRE family watched me turn into an emotimonal pool that only cared about his wellbeing. He comes from a family of mental illness and his mother is bipolar. We were staying in a home where I was sexually harassed by his step grandfather, threatened by his mother, scratched by the cats, inhaled animal dander constantly. All because the family made me feel bad about temporary separation until we were more stable. I wanted so desperately to please not only him, but his family. I lived there for about 5 months before I had my baby shower, in which it was the happiest I'd been in close to a year. And after coming back from staying with my friends and sister and mom for a girls weekeend. The very next day, I get back...his mother and him are arguing (which was a common occurrence) and she tries to pull me into the argument several times as they and scream. She calls me a demon for no reason, calls the cops on him for no reason, and I have finally had enough. I pack my bags. Didn't make him at all. He comes with me, my parents pay for a hotel for him to stay in for a week because his grandparents defended his mom, called me out of my name, and he was promptly told he was going to be evicted. Well, he doesn't have the best relationship with my family and they weren't going to let us stay together in the house, so he stays at a homeless shelter for ONE DAY. He wants to go back to his grandparents house, they yell curse, same thing, but don't want me there. I curse, which is completely out of character for me, but I was pushed and block them. He then argues with me the whole day, and he's suicidal so he tries to jump out of the car several times as I'm driving. He walks off after we pull up to my parents house and the I can't find him...seeeing as he's suicidal and has tried to kill himself before, I file a missing persons report. He calls me the next day and mind you, I couldn't sleep. I cried all night because I was concerned. anyways, fast forward to today, he tells me to be the bigger person and apologize to everyone because their feelings were hurt even though I didn't do anything wrong to begin with. Tells me he's filing for joint custody because we're separated after a long argument and finishes it off with not only throwing my under the bus but blaming the whole ordeal on me. Sorry that this was so long, everyone but I was so broken inside earlier and now that I'm feeling a little better thought I'd share my story finally. I just need someone to talk to.
