I feel so bad for you. Our H's must be on the same psychic wave length. I can so empathize with your feelings. Your normal everyday sort of relationship needs become as nothing in the face of the black hole of your H's depressive tendencies. This may sound crazy but I'm sure you can understand this thought. After my H's tantrum, I was actually having the thought that I ought to withhold sex from HIM just to show him how serious I am about the fact that he needs to get counseling and/or treatment for his depression/anxiety and the related problems he has with work and sexuality. Though I would probably get quicker results by withholding my cooking (LOL but in a sad way.)
