I catch a co-worker looking at me, when I look at him he quickly turns away. He has a girlfriend. Why??

This behavior occurred months ago and I sent an email trying to find out his interests outside of work. I found out he has a girlfriend and at that time the glances subsided. Now a few months later, the glances are picking up again. I'm confused as to what it means. I promise I'm not picking my nose. lol
