How far will your partner go to use you?

I never really had to deal with a difficult relationship until now. When I was in high school, I was something like a player. I had s3x my first time when I was 7yrs old. No kids. Anyway me and my girlfriend had been together for almost 3yrs. When I met her she said she had a car and a job but later I found out that wasn't true. She didn't even have her high school diploma or GED(and still don't). So I said I would take care of her while she looked for a job and went to school. Ok so I got her a job, at this retail store, and even trained her on the job. At the time we had an apartment and was happy. So my cheat azz wanted to save money. We ended up moving in with her mom. The GED school was right around the corner, really it was. Eight houses down and two houses over and you would be there, a small child could do it. She ended up not going to school. Things got bad and she ended up losing her job. We then moved back to Cleveland OH. Now we are suppose to get married but guess what, she is currently married to someone else so we have to get her divorce. Now the weird thing is when she was with her husband they would fight. They had a baby and he would beat her and caused her to lose the baby. I am 22yrs old, she is 23yrs old, and he is in his 40s. The typical Jerry Springer case. Anyway she said he would say things like "get up and do something", later I found out what that meant. He quit his job because he thought it was unfair that he worked while she sat on her rear. My family say I'm stupid and that I could of went to college(and I will go). She jokes to her friends and say "my boyfriend takes care of me I don't have to work'. They call me a bum and make fun of me. I have a high school diploma, I have a job, and I don't have a criminal record. Why can't I leave? Years ago when I left she took all these pills and tried to kill herself. She said she didn't have anyone and she don't. Her mom don't do anything for her. Her husband laughs at her and her father is dead. Her and her father was real close. She even got my name tattooed on her chest. I know she has problems. I was at the hospital when she tried to kill herself. I think she is Bi Polar. I have some feelings but I don't want to be with her. She's a crazy bltch. She knows where all my family live and where I work. Everytime I try to leave she jumps on my things and starts crying, begging me not to leave. From what I hear she put her husband through h3ll and tried to make him look bad. My only option is to relocate on my job and move far away. She needs to be on meds and social security. She is just not motivated to do anything. I am like her father and I don't want that. I learn from others like my high school friend who was killed by her husband only so that he could collect her life insurance. They both had kids and he hired one of his friends to kill her. I don't even want to be in another relationship. I always told people that there was no more love in this world. I don't want this to happen to any young man. My advise is to get a women with a college degree and a career. Even though she makes it seem like she loves me I know she don't and don't care. I just want out and need help.
