Most Helpful Girl
I know I get pretty nervous/awkward around people I like. But it is possible he's just an awkward person and you can't recognize that awkwardness with other people but can obviously feel it when it's directed towards you. Have you tried texting him? That can be less awkward, especially people who are predisposed to being awkward. It might be the best way to try and flirt with him if he's acting like that around you.
