How to know if a geeky shy guy likes you?

Is see him everyday in the library somehow I feel conneected to him. He's really shy we've had a lot of eye contact in the library, but when I meet him in the hallway he'll look away or even turn around :(

Should I just go sit next to him and ask if he wants to have a drink with me?

Do they in general even like girlie girls? Because actually I'm a kind of geek myself but it don't really look like a typical geeky girl... Because I'm more a girlie geeky girl :)
