We ML usually every other day, if not more often than that, I am affectionate, loving, I will just give him a kiss on the back of the neck or just touch him when I walk by, I talk to him about his interests and work, I make sure we have "us" time, just the 2 of us, no children -- either dates or just making sure I stay up after the boys go to bed and spend quality time w/ him either talking or watching a movie together, etc.
All that sounds really good and I'm sure it must help. But do you know exactly what he was unhappy about? You've done all those things, but you might still be missing something else that bothers him. Have you asked? It sounds like you are trying to "do" things together, but are you two "connecting?" Maybe that is something he gets from the OW?
