Suggest Treatment For Recurred Addiction To Alcohol Post Rehab

My husband went to rehab 10 years ago for alcohol/cocaine/crack. we met afterwardsand have been married 8 years. He went to AA for the first 6 mos post rehab, but then started drinking a couple beers a night (2-3) which grew to 4-5 per night. After a couple years together, during a stressful job change and when our only child was about 1 tear old -He relapsed on crack 3 or 4 times (this was 6 years ago), after which he was very remorseful and promised to stop drinking. Not drinking lasted about 2 weeks.First he started back at a 2 beers a week night and 3-4 on weekends. However the last 2 years, he has been drinking 3-4 beers a night, and again during a stressful job, he has just relapsed on coke (so far a couple times that i am aware of). I had told him to leave (with the help of his parents), but regretted it -afraid I drove him to the crack house. He is very remorseful and feels worthless. Afraid of him dying, I asked him to come home, and told him we would get through this together. Our child is now seven. I also have been to rehab for alcohol/cocaine, and while I too have had a few drinks at an annual Christmas party or wedding, I have never gone back to regular drinking. we have fought often about the nightly beers, but he insists that 2-3 beers a night is normal. I don't know how to reach him.. I love him and believe he wants to be stronger, but he does not feel that AA can help him. I would appreciate any input.
