He has Hurt me Physically 3 Times, should I stay or divorce? Please help!

We've been married for 11 years. Together for 14 years. We've had a very difficult marriage for a long time. Mostly because of my in-laws and how my husband put his and their needs ahead of ours and mine. My in-laws are extremely difficult people to say the least. He first punched me in the leg in 2004 after he pushed me down and I kicked him, this was while I was recovering from surgery having precancerous cells removed from my cervix; my therapist at the time said I was culpable. He then later grabbed me a couple of months later. Just this past January he also grabbed me and threw me against the wall after I knocked over his tool box or he says I trashed it. Now I know that I can get nasty with my words, but my current therapist says there's no excuse for him to do that. I have hit him back in my defense, but he's 6'1" and 230 pounds, while I'm only 5'3" and 140 pounds. He could seriously injure me if he wanted to. Recently he said that I don't have to see his family anymore and if we ever have kids they don't have to either. I also told him if he ever hits me again I'm calling the cops. He said he's never going to hit me again. We also own a house together now. I don't know if I should stay or leave though. I do love him still. Although the love is very different now. The problem is I struggle with psychosis and depression and anxiety. I've had five psychotic episodes since 2004, and I cannot keep a job because every time I try to work I end up in the hospital. I don't know if it's because of how damaging my environment at home can be, but I also know that I do have issues mentally regardless of my marriage. But they also didn't worsen until after I met my husband at 19. I'm 33 now. I don't have the option of staying with anyone. I also had an affair in 2009 because of years of dealing with his and his family's emotionally abusive nature (his father is an alcoholic, his mother is neurotic and overbearing and manipulative, and his sister is a stupid bully). Plus, he ignored me sexually for many years. Although there's no excuse for the affair I had. We do have some good moments daily. We get along most of the time. He is also seeing a therapist for individual counseling once a month and I go to a different therapist twice a month. Should I hold out hope for a brighter future together, or should I try to figure out if I should leave? I hate the thought of never having kids. I hate the thought of him moving on and finding someone else and having kids and then I will probably end up alone forever trying to keep my mind straight and keep myself out of the hospital. At least I have him to take care of me if I ever end up in the mental hospital again. I don't know what to do and I really need some honest advice. Please someone help me. :(
