Should I try AGAIN?? Abusive (formerly?) estranged husband.?

My husband and I have been living apart for almost 2 yrs. We were together for 11 yrs. While we were together, he was physically, emotionally and mentally abusive. We have an 8 yr old son together and he's wanting to reconcile. While we were together, he ruined every job I ever had by showing up to my work and accusing me of sleeping w/my clients or calling several times/day. It was easier on my nerves to stay home and take care of the family and home. Now I'm in school for nursing but I haven't been able to find a job so money is TIGHT! When I got and Order of Protection on him, the Judge ordered me to pay all of the marital bills w/out a job and $100/wk. child support. Well, I've been living on the child support. We have no clothes and nothing new. The only time my kids get anything is when they're w/him so they're begging me to reconcile. I'm not sure if that's the best move for myself or my kids, even though they're begging. He says that the abusive days are over and he wants his family back. What do I do for money if I don't take him back? Should I take him back? We don't even have furniture in our house right now. I can't find a job, still looking though. What should I do? Please don't criticize me! It's an open question, not addressed to anyone and if you can't offer positive advice/options for me and my kids then don't answer this question. I've got enough on my mind right now and need positive energy. Please and Thank You!
