As for your sitch, personally I would feel uncomfortable going of the DB path right now. As has been stated in the DB/DR books (and I take even them with a grain of salt) many C's are interested in the individual health of their patients, sometimes much more than the health of the marriage.
This is one of the differences of Solution Based Therapy (DB) vs. Traditional Therapy. I went to both. It was my personal experience that I found Solution Based to work better in my sitch. Its one of those Your Mileage May Vary sitchs. The only reason that I went to the traditional therapist was because she specialized in addicts, and families of addicts...I wanted to get a feel for what I was working with in regards to Dave's alcoholism and depression. Once I understood that, I stuck with Chuck at DB until I moved on. I found that by having goals or a game plan I was much more focused.
