Other employees think my boss has a crush on me. They say he stares at me. A few months ago they said he was following me with his eyes. He is corporate and only there for a short period of time. He is married and I am involved with someone.
You have one of those situations where it is better to leave things as they are, rather than trying to find out if your boss is attracted to you—or if he has a crush on you (which is a different thing). If he is an executive or closely aligned with corporate management, he could lose his job or at least lose his reputation, if it was thought he was having a relationship at work. That could lead to the loss of his marriage as well.
