Is there any way to address that in DBing other than looking good and GAL?
The spark is gone because he's depressed, and it can't return until he comes out of the depression--so, no, there's nothing YOU can do to change him and bring it back.
However, looking good and GALing will make you feel better about yourself, which will in turn make you take any pressure off your H, creating a friends-relationship that *might* later be the basis for something more.
So, what can you do to become the confident girl you used to be, the one that attracted H in the first place? At the same time (I believe you read Love & Stosny's book), how can you avoid triggering any feelings of shame in him, so that any negative spark-killing emotions are gone?
FWIW, I agree with CityGirl that your C needs to be for you alone at this point.
