Never understood the whole "must keep your wife hidden from the world" jealousy nonsense. As long as you trust each other then it wouldn't matter. When I was in college (this happened more at this time than now) my ex got hit on and she would just reject them. There were very few times that I had to get involved (mostly at clubs with really drunk people). Does this guy expect his wife not to go anywhere without him? I can't imagine having that kind of insecurity.
