New boss acts strange around me, and I don't know why?

I recently started a new job and my manager acts very strange towards just me. During the first couple of weeks, he acted as if I didn't even exist. He wouldn't look at me even if I talked to him but gave the appropriate attention to everyone else. At first I just blew it off thinking that's just how he is, but after a while it started to frustrate me. I didn't do anything to make him hate me, at least I don't think. After all, I just started the job! One day he finally made some eye contact with me and I was completely surprised and the longest conversation we had was when all the others were out of the office and it was just me and him. Now he will make eye contact, but still avoid me sometimes and rarely makes conversation. I don't have any issues with any of the other managers who are also guys which is why it's so strange to me. I can't even compare this to other girls, because I'm the only girl in our office.

There's two options I'm thinking of: either he's just a guy who wants nothing to do with any girls, or he has some feelings towards me and is trying to hide it. Any ideas?
