Yes.
This is His Addiction and therefore it needs to be His Recovery.
In my case, I found that if I tried to get involved in the solution ~ then I would be blamed during the failed attempts for not being supportive enough or not having the right plan of action.
If I stay out of it, the one with the problem can own the solutions.
