Addiction Therapy only works if the person is in it willingly. I suspect if they are in therapy against their will - it will trigger lots of negative "stuff."
As for marital therapy - we went early on in our marriage - and it did exactly like you mentioned - it made my AH feel more entitled to his behavior. The therapist wouldn't label AH's drinking - only said, "if it's irresponsible or causing problems, then you should examine that." And then turned to me and said, "AH has a mother, and it's not you. Stop nagging him and trying to control him."
I left PISSED OFF. AH drank even more, and harped on the one thing therapist said to ME! But, the therapist was right. He couldn't tell my husband he had a drinking problem, anymore than I could. AND, I was nagging my husband.
And just for the record... I won't waste anymore money on therapy for my marriage, or my husband... because according to him, "I don't need it!"
