For clarity, what does your H say when you tell him you want more? Does he just brush it off? Does he try for a while and stop? Why does he keep going to the retreats? To try and find ways to meet your needs or to get you to meet his? Or both?
He promises to give me what I asked for. Sometimes he'll do it for a short time then stop (a week at most,) sometimes he doesn't do it at all. I don't know why he does the retreats, but it's always "new information" to him even if he's heard it 100 times. The only thing I see come from it is that then he can claim "effort."
