Revelations are what we make of them. Whatever fates, gods, or the universe brought this light into his clouded thinking makes no nevermind, right? As long as he hears the call and follows it.
I agree that your recovery is foremost for you, so shall his recovery be for him.
Be an example to him that actions speak louder than words, that compassion can be given without condoning, and that living amends goes beyond any apology.
I certainly hope for him, that this is the first step in his recovery, and I also hope that whatever form that takes, you aren't waiting for him in finding yours.
Best wishes!
