Hello Penny,
It certainly can happen for him, but nobody here has a crystal ball. It is impossible to see into another person's heart. And you are the only one who will ever know when enough is enough for you. If you have been to alanon meetings, then your certainly know that our focus here is on getting past our own obsession with what addicts do, not on ways to fix them.
If you want examples of how we fix OURSELVES, there is a lot of experience, strength and hope here.
