I feel that I shoulda, woulda, coulda, done more to intercept the desire for him, and set a better example by not having wine in the house or redirecting his attention the MINUTE he got out of rehab to something positive. I didn't realize that I inadvertently facilitated him!
His behavior directly out of rehab indicated he didn't get much out of the program and hadn't changed at all. Directly going for a drink was his choice, not yours. I can't see where you facilitated.
If he had asked you to keep liquor out of your home, it sounds like you would have complied, he obviously would have found liquor elsewhere if he didn't find it in your home.
