I wouldn't have punched the man, but seriously continuously complimenting your girl is not cool. It's not that you don't trust your girl, it's that you don't trust your guy. If he's constantly pining over her then he's obviously the jealous one, and that kind of nonsense shouldn't be tolerated.
For most guys I'd say you just have a talk with them and get them to stop. But if he keeps going, is untrustworthy, scrupulous or whatever then you've got some cause for concern.
Of course you don't want to get all paranoid or angry. Mostly because then the girl might take it the wrong way and get all "Bawww, you don't trust me? You're a jealous paranoid idiot." Then you gots to be all like "Bitch what I tell you?" and backhand her and get her to make you a sandwich and hook up your Xbox so you can get your hardcore Madden on y'know.
