I guess... he thinks I am dumb? Is that it? We're in the same very small field so maybe I should just ignore him?

There's 10 of us grad students and we all get along, and then there's Mike who's really friendly with everyone but pretty much ignores me. Unless we're at the pub, then he always smiles/hugs me and its weird because it's like he's insisted on never looking at me ever unless he's drunk. Even when i speak to him he sort of looks..not really at me, and if I'm sitting across from him he just looks uncomfortable. Except for one time I caught him staring at me but he just looked away. I mean I am considered attractive but...is that it?

We've shown each other our thesis/work and everyone else, seems to have no problem with what i'm doing and thinks its really interesting/different but he has zero reaction besides shrugging. And he tries to correct me on things that I have done succesfully before by saying its not really possible. What?

I mean ok, I'm an idiot when I talk about anything pretty much because autism?/nerves so I try not to talk too much but I get good responses to my papers. But everyone else doesnt seem to have a problem with me so I'm confused.
