ADHD spouse's approach to therapy

My husband has been seeing a therapist for approximately 8 months.  I encouraged this and still think it's a good idea.  But my husband doesn't seem to be making progress.  I asked him today if he exposes himself to the therapist.  He asked what I meant.  I said I meant showing his vulnerabilities, saying things such as, "I've been seeing you for eight months and I'm still depressed" or "I'm tired all the time, the kind of tired that makes me unable to get things done."  My husband said that no, he doesn't talk to the therapist about these things.  Knowing my husband as well as I do, I'm not surprised but I'm very disappointed and frustrated.  What does he think the therapy is for (aside from getting me off his case, something that he hasn't succeeded at either...)?  Have others experienced this with their spouses or partners and therapy?
