-Show interested in the things he likes even you could care less about it. Takes some time and watch a show or sports with him. Be in the room while he's playing games. Every so often ask a question about something you don't know about what he's watching.
-Listen to him to find clues about something he may be wanting or would enjoy, the surprise him with it. Shows that you listen when he talks.
-Give him back, foot, shoulder massages.
-Simply let him know in words that you appreciate him and tell him exactly what you appreciate about him.
I tend to see that men are no different from us even though they may not show it. Just think of what would make you feel appreciated and loved, turn around and do those things to him!
