Lexie, let me clear that up. If the "bail-outs" become repeated, then you leave and have him has his brothers, mother, whoever take over. Do whatever it takes to keep him from draining the family finances.
I'm not an expert like you guys, but I came from a family with many substance abuse issues, and I really believe in Zero tolerance. YOu have to allow the alcoholics actions to catch up to him to the point where he realizes that it is far better to be sober than drunk and that he HAS to change. Let him run out of options. Again, incentive for change.
No calling into work for him, no driving him to the store, no picking him up when he hits rock bottom. He has to suffer the repurcusions of the drinking. Anyway, that's how I feel.
