While I didn't quote you, to me, it sounds like he doesn't have depression but, another mood disorder. I am thinking Bi-Polar Disorder. One of the behaviors of Bi-Polar Disorder is, the patient 'projecting' their problems on to someone else, as their way of not taking responsibility for their behavior.

My fiance was diagnosed with Bi-Polar Disorder in 1999 so, I know what it is like.
