I think it's not your job to be his therapist. I think that is a therapists job to do that kind of stuff. A therapist can work with someone when they fail, lie are successful, etc. and help them through it. A therapist is qualified to work with someone and has the training on what an addict is going through, a wife has a hard enough time trying to understand and take care of herself.
A bad idea if you ask me.
