How do you avoid a married man appears to be interested?

Anonymous
This man flirts, is constantly staring at me. He looks in my eyes when ever he is interacting with me. He has touched my hands when handing me something and once he placed his hand on my lower back to guide me out of the way. He is supper nice around me, and tries to impress me. He knows my name, but we've never been introduce. We work in the same building but different companies. Unfortunately I have become attracted to him, but I didn't know he was married. Know that I know all I can do is stay away from were he works. Its not easy but doable to some extent. I'm hurt and saddened by the whole thing, because I thought he was interested. Although I avoid him and no longer will even interact with him, he still finds a way to be around, just so he can stare. He's behavior is unacceptable. I may be single and lonely but I'm definitely not desperate. I'm an attractive woman that is in good shape, and I don't look my age. I consider myself way to good to be second best to anyone. Not that he's asked me out or anything, I don't understand why he does these things, its all pointless and a waste of time and energy. There was a time that I wanted to be friends, so I can get to know him. I no longer want that, all I want is to be able to get him out of my head.

Any advice would be great. Thanks

I know my role is to stay away and never encourage such behavior. I'm sure he's just looking for attention/ego boost. Thanks for letting me vent, and your responses. This is not something that I can speak to my friends or family about. Some how all though I've done nothing wrong, its I still feel badly about it. Its a terrible thing when anyone plays with your emotions and even worse when you allowed it to go on for so long although I didn't know he was married till a few weeks ago.
