Should I fix my marriage or leave?

Every morning since I have gotten back with my husband of six years, I have found myself to be unhappy and lonely. I left my husband in our third year of marriage, he became very manipulative, verbally, and physically abusive. I thought I could help him change. Of coarse I was wrong. Maybe I changed him a little. But, it took too much time and heartache. In sense, I feel lifeless, my soul is torn. Who am i? After leaving my husband, I had no job, barely any money, and moved from place to place. It was so hard for me as a woman. Although I became strong. I really got myself together. While I was rebuilding my life, my husband's was falling apart. And by that, I mean literally. He struggled with ptsd from the war. (Prior Military) Although he says his violent behavior is from being in war, I believe that is far beyond that. Not only was he violent, but he constantly accused me of seeing another man. I never did see anyone while we were together. He refused to get any kind if psychological help. He carried a gun almost everywhere he went. One night, while we weren't living together, he got into a fight at a house party and shot the guy. The guy lived, thank God. I only heard what happened from a mutual friend. At first I didn't believe her until I ended up finding legitimately. My husband was ignorant and didn't want to tell my anything. I pleaded and begged. He only pushed me away over and over again. I saw him every once and awhile. I lived him still, I cherished each moment I spent with him. Even though he hurt me. I found leaving him, the hardest thing to do in my life. Eventually, I broke all contact. He left off to another city four hours away to live with another woman. Although I broke contact, He would occasionally call me. I tried to ignore every call. The times I did answer, he was just calling because, he was having relationship problems with the other woman. I would just hang up. During this time, he was also running from the cops for the previous incident. I knew that eventually he would get caught. Call me or somehow I would be involved. It happened about a year later. I had just about finished taking a few classes at a community college and then I got a call from my husband in jail. I already knew what was going on. Me being the person that I am, I did everything to help him. I contacted his family, a lawyer, etc. I was amazed to see that his "up to twenty year" sentence, went down to a ten year strict probation. I was so angry, confused, and emotionally tired. My husband finally showed his appreciation for me. He has changed for the most part. I've seen him do and say things that he never did before. But there were still times after he got out of jail where he betrayed me again. Just not as bad. We are still together in a way. For me, I am just alone. I want to forget everything, and move on. How can I? I felt better when I was separated from him. I recently quit my job because I just couldn't be at work with all this stress and depression. It was killing me. I felt as is was going to breakdown at work. I couldn't manage to bring myself to doing my job. I need support. I want to leave again. I just don't know where to begin. Please help

Get out now, whatever way you can,SS! you cannot solve this man's problems for him - he needs to first recognise he needs professional help and then seek it out. If you stay, you will be dragged further down with him and maybe even killed. Go to family, friends or a shelter but get out! He cannot be saved by you - he must save himself. You owe him nothing and whatever happens to him is his own choice. Sometimes people only realize they are going wrong when they find themselves alone. Leaving him could be the incentive he needs to find help. But don't be sucked in by his excuses and pleas anymore. Violent people don't change unless they get proper help, years of counselling. He is blaming everyone else for his problems at the moment and needs to take responsiblity for his own life and decisions. Don't get hooked on abuse. Leave and don't look back!
