I know exactly what you're talking about. I know that I needed to see my H become more affectionate. I needed him to begin giving me the "just for no reason" kiss on the top of my head or cheek JUST so I would feel like the distance between us was closing.
The way it began for me is I started "touching" again. I began (which I hadn't done for years) just touching his shoulder as I went past him or reaching out and lightly touching his arm when making a point in a light hearted chat AND I began kissing him on HIS cheek just for no damn reason as I left the room or walked off in the yard or something....and guess what? Yep, he started doing the same. It seems in many ways that they don't initiate touch because THEY feel dirty from what they've done and crazy as it sounds they are hesitant to touch us with their self perceived "unclean hands" T2
