Actually something similar happened to me I just started seeing this boy and I got a crush on him I see him like every single day at school nonstop (it can't be a coincidence) and he's noticing that I'm look at him (~cough cough what he's cute XD) but yea I got the feeling he thought I liked him cause I usually see him a lot (no joke) and I look at him cause I started to like him but after a while I started like this other guy and dated him XD......
But If this guy your saying is looking at you maybe he has an interest in you...you should try to talk haha try teasing him a little (its fun to tease) :)
