I asked H to leave; regret-now what?

Good point about going dark.
Married close to 3 years. First 8 months was great and he helped me a lot through my breast cancer diagnosis, surgery and treatment.I had found out about BC the day we returned from honeymoon. After primary treatment we began building up his business, going for his "passion" and I financed equipment. I returned to work and he gradually began working 20-30 hours on the business, in addition to regular f-t job. I was placed on medicine which caused a lot of fatigue, experienced anxiety, and 'menopausal' symptoms. Financially we were both doing well.

During that time he asked if his teenage son could live with us since he hated being out of state-I said sure. His son had some behavioral problems and H had difficult time parenting. He had been a part-time dad & inconsistent since his son was a young boy.My two teenagers have lived with me since my divorce from their dad 10 years earlier-both do okay in school and we have a close relationship. Seven months later he takes his son back to his mom-without talking to me- and said his son did not like the way I looked at him and we were too strict. We had noticed some drug use and skipping school. Later I talked with his son privately and he said this was not the reason; it was that his dad was too strict. We saw him for 3 subsequent holidays and things looked good between his son and me.Currently son is in rehab and still lives with his mother.

During this time H started working 30-40 hours on this additional business and was doing well financially. His personality changed in that he started being boastful and name-dropping to others. Much of his weekend nights were taken up with business (music). Although we had a few talks about "balance" and needing to spend time together, he would acknowledge and promised we would do spend more time together, but it never happened. I did become a complainer and nagged and we grew more distant. I became more lonely. He rarely invited me to any functions. During this time his daughter, 20 y.o, was having problems with spousal abuse and she was in a "safe house" with her two children. H was under a lot of stress and was even more distant. (while we were dating some similar incidents with his kids occurred, he was stressed and he broke up with me for 6 weeks, then apologized and pursued me again).
On my son's birthday he decided to do a gig, at the last minute, instead of joining us. I got angry and we had an argument. I rehashed the above compliants and told him he was in danger of losing me and that we should separate since I was living by myself most of the time. Five minutes later I took that statement back and said I spoke in anger and I was sorry. He appeared to forgive me and said he didn't want to lose me, he loved me, I was a good woman, etc. but then he went onto do his 'gig.' Two days later, after another gig, he doesn't come home, all night, didn't call until 8:00 a.m. First I was hurt and as the night progressed and I found out he wasn't in an accident or in jail, I became very angry (no cursing or throwing things). When he came home I asked him to leave. He didn't argue against it and just said "I was pissed off at you for telling me to leave the other day, so I went out with some friends, after the gig, I got drunk and passed out in my car." While that may be true, he was able to get up and call his place of employment to call in sick at 6:00 a.m
It doesn't appear to me that H wants to be married. I know I handled this wrong, by overreacting and telling him to leave. I do regret this but now I have to live with the consequences.
I want him back because I have seen that other side of him (the unselfish, kind side)but now I question his integrity and character. I'm vacillating on this since I don't want to be hurt again.
