How do you know if your co worker has a crush on you?

Watch out! Office romances seldom turn out and can get ugly if the two should split up. It can cause great pain if the couple don't continue to date each other. Sometimes a boss can be just nice to their employee so be sure you don't get being nice mixed up with a crush. If this guy is interested in you (and NOT married) he'll ask you out in good time and you'll have your answer. Marcy
