Why are most men jerks? HELP

Husband and I been trying for 3 years. I gave up and he said no matter what he wanted me pregnant no later than January 2016. Found out February 1st I was prego. Now he's the biggest jerk. He down played to his parents we weren't even trying. He has no heart. I'm on bed rest because I fell and hasn't shown any emotion about it. He left me all alone on Valentine's Day knowing that is my favorite holiday, im begging him to love me and he doesn't. Instead he is trying to turn it on me because I told him I was going to find a lawyer because of everything he keeps doing and he's making me feel bad I'm doing that. But he is very verbally and emotionally abusive and not just to me but to my children and I'm not sure what I should do. Should I stick it out or just move on? Any advice would be appreciated. I think my main concern is I don't work before learning I was pregnant I learned I had fibromyalgia, lupus and also a mass in my lung so I haven't been working because of those illnesses. Now pregnant none of that matters and I'm not sure how I will survive without his income. I don't know anyone where we live because me and my children moved here for him once we married for his job so I feel I'm stuck.
