Ice cream, a listening ear, a ladies trip, hiking, anything to keep her occupied. If it's a guy well, no trip LOL
You can do a guys' trip, it just helps to be a guy yourself
From a man's perspective, hunting, fishing, hiking, drinking beer, shooting, the focus stays on giving them something else to think about even if the activities change. And needless to say some activities don't play nicely with other activities (beer and fishing make a good pair, beer and shooting less so).
