Hi Tautologic,
I think that it makes sense to discuss the "fallout" first and then together you can make your way to the underlying cause. So, rather than saying it is the depression that you need to deal with, and that causes every problem, maybe you could describe the problems first?
You might find that some of these problems and issues have other causes, and that your husband's depression is a manifestation of other issues as well?
I know that when I began therapy a year and a half ago I had very different ideas about the root of my problems than I do now. I don't mean to minimize the effects of depression because it is difficult to live with. It's just that I have found that our problems are rarely as simple as we think they are .
I wish you both well.
Good luck!
Peace
