He has told me that he knows that he loves me because he hates to disappoint me. Maybe on some level he is choosing to disappoint me in order to feel his love.

I don't get this reasoning at all. I think you are way over-analyzing instead of looking at the most obvious and simplest answer: that your H feels like he is disappointing you, it is causing guilt and depression, the SL suffers, and the cycle begins.
