I think you were the wise soul who once pointed out that it was more relevant whether you were the one who was HD about working on the relationship, rather than whether you were the one who was HD or LD about sex.
If this is the case, I think you and I find ourselves at similar crossroads in our relationships. I guess I'm still kind of hopeful because even though my H isn't really working much on our relationship right now, he has led me to believe that it is on his "to do" list for the future. Maybe your H hasn't really lost all hope or initiative. Do you have any idea why he is unwilling to go any further to meet your needs when I'm sure you have spelled them out quite clearly? Is he just being stubborn or could there be some issue of integrity he's not communicating?
