My therapist asked me again, the other day, if I still wanted my marriage. I answered, again, I still do. This is the hinging point. If I decide differently, then they will help me deal with that decision. Until then, I'm given advice and ways to change things in my life.

Depression doesn't allow instant changes in behavior. In fact, the sufferer needs the constant medical attention to keep them healthy. Hoping for anything else may be a false hope, or denial. It's what it is and it can be a hard life to deal with a depressive partner. What you do with your life shouldn't be destroyed by this partner, or allowed to stop with your efforts as a caregiver. If you can't accept what's offered, then it might be time to move on to something else.
