No, honestly I don't have the experience with a married person at work, who plays these games.
I don't know what he is contemplating, nor trying to accomplish. However, as you are clearly not interested in his advances and games, consider going to your supervisor. Report his inappropriate behavior. Most workplaces have rules regulating behavior of the work force, and his idiotic games are not beneficial to the smooth functioning of your working enviroment. It probably freaks you out, which is not good for your jobperformance

. Be honest, be factual when you give your report of the situation.
