For me, AA and rehab didn't "work", until *I* did.
When I was ready to get sober, it didn't matter HOW. Until then, it was all peeing into the wind for me. This last time, when I was finally TRULY ready, I went to Outpatient Treatment and AA, in addition to using other methods (CBT and AVRT).
I would say watch what he does rather than listen to what he says. The rule in our house was one year. We started marriage counseling and "dating again" before that, but recommitted at my 1-year sober mark. That was almost 5 years ago and we just celebrated 15 years of marriage (and it is better than ever). The year went by fast.
Glad you are here.
