You never know, this MIGHT actually force him to look at what he is avoiding.
When we alcoholics are in recovery, even when we really WANT to do it right, it's easy to screw it up. Our priorities may take awhile to be sorted out the way they should be. SOMETIMES a psychic "slap in the face" is what it takes to wake up. Only time will tell whether that's the case here. My guess is that his AA friends will put a certain amount of pressure on him to start putting more effort into his home/family life. Don't underestimate the power of other alcoholics gently (or sometimes not-so-gently) suggesting that he get his head out of his butt. Of course, whether he TAKES this suggestion or not is up to him. If he trusts them, and wants to stay sober, it might have impact that your own voice did not.
