My wife wants me to go out with a bunch of people from her work, but I know there is this guy that will be going that is constantly hitting on her....I don't know how to act.....? I don't want to come off as the jealous husband (which I'm not), but at the same time I want this guy to know that I'm not going to be all chummy with him, and I don't appreciate his actions when he knows she is married.......any suggestions?
