Need advice...or real life experiencess...please!!?

Going to try and make a long story short....three weeks ago I left my emotionally/verbally abusive husband and moved three hours away, with our child (he's 4), to be with my family. On Easter Sunday he had threatened to beat the **** out of me and kill me. That was my last straw and from that moment forward I started planning my escape. With legal advice, I decided the best thing to do was move away as fast as I could. Over the past 4 years the emotional abuse, suicide threats, and anger has gotten worse and worse. I begged him numerous times to please get help...he always refused to go to counseling or get on medication. I tried so hard to make things work, I walked on eggshells daily, feared the next time he would get mad, and got to a point that I didn't want to go home or spend any time with him...When I left him it sent him into what he calls "crisis" mode...and it got him into emergency counseling and got him in to see a psychiatrist for free...he was diagnosed bipolar phase 1, and has been put on depakote, which I has suspected for a very long time. He never thought it was real, he said that it was just people around him pushing his buttons the wrong way and making him angry. He says I never should have kidnapped his child away from him. One minute he says he's going to fight me for full custody, the next he's saying he doesn't want anything to do with either of us anymore, the next he's ready to kill himself because he can't take the pain from all of this. He says I should have NEVER left a sick man like this...I could not take it anymore. It has put me In a depression and caused my concentration to be absent, along with my anxiety and OCD to be very bad. I basically left him with nothing because I was the only one working and paying the bills, while he was in school and I was having to help him with his homework cause he didn't feel like doing it...I'm also In grad school and take care of our child...he did nothing around the house to help me, nor did he...
