i wanted to add that i understand about the "physical" part of your marriage, the hugs, the little kisses, the holding of the hands, i get it, but you can do something too.

maybe when you come home from work give the kids their baths and put them to bed, while your wife cleans the kitchen or puts a load in the washer, and then come together just the two of you watching whatever it is on tv or drinking coffee or wine together and talk about each others day while your giving her a foot message.

do something where you can reconnect with your wife.
