Guys: Are attractive guys insecure?

I recently met a very attractive guy. For some reason he was acting very hasty and refused to make eye contact when he was talking to me. I thought that maybe he has a girlfriend or he is married or he might not like me. I noticed other women were trying to flirt with him but he seem very confident and relaxed around them. Its confusing because I also noticed that he keeps looking at me but doesn’t talk to me and wants to ignore me, I’ve lost count of the number of times I’ve caught him staring at me. Anyway, it’s led me to the thought that perhaps he might be shy or insecure.
