That is interesting, LFL, because my H has said to me that there were times, even early in the marriage, that he didn't feel I really cared about him. My H is a sensitive soul, and he kept his feelings under wraps. And I didn't listen to him, or convey my feelings, in a way that he needed. Fear and insecurity then rule the relationship, and love, faith and trust erodes.
Your H sounds very similar to mine NJ. He WANTS to have an intimate R/M but he just has a hard time figuring our how to get there and maintain it. Me too I guess.
