Long post. Sorry in advance.

I'm pretty sure my husband resents the hell out of me, and may even want to end the marriage. I have bipolar, anxiety, and ptsd, plus a lot of physical medical problems that have kept me from working for a few years. When I started job searching, I found out I'm pregnant, so I backed away from the job thing so I wouldn't possibly have yet another miscarriage - which he seemed to support me on - but lately he's been at me that I need to get a job so he doesn't have to find a better paying job because they all drug test and he doesn't want to quit smoking weed. I've also got really terrible teeth problems, made so much worse by pregnancy, and there aren't many things I can eat. When I ask him if I can get such and such to eat, he asks if I'm serious because it costs money and I probably won't eat it all. Wouldn't be too big a problem if he would let me get these teeth taken out, but he keeps coming up with different excuses of why I can't get it done. He recently dropped his phone and the screen cracked, but it's still completely useable. He's saying that my dental work will have to be put off again because he needs a new phone. I'm less than a month from my due date, but I've been dilating and having more serious contractions for a couple weeks now, and he's been coming home from work hours late every day. Tells me he's working over. But he supposedly just got a raise, and his checks are less and less each week. I confront him on it and he tells me that he's been getting off early. I ask why it's taking him an extra 3-4 hours at this point to get home and he changes it to taking long lunches. Finally he tells me that he's been going to a friend's house up the road from work to hang out and smoke. Wouldn't be too big a deal if he'd answer his phone, but I can never get in touch with him after he's gotten off work. Every time my hormones get the best of me and I cry about something he tells me I need to stop and calm down because I'm being ridiculous and making him feel like shit or look like a bad husband. He's been treating our dogs like shit, too, lately. If he can't come home, get high, and play a fucking video game until a few hours before he has to be at work he's a total dick to all of us. I'm wondering if it's even possible to fix this relationship. He's also told me for a while now that he wanted to wait til he was in his 40s or 50s to have a baby (he's 27, I'm 26) and that he's also thought about leaving me a few times during this pregnancy because I'm so unreasonable and not getting much done around the house. Should I even try anymore?
