Why does he look at me like this?

The best way is to find chances to tell him how you feel, and whether he likes you or not. If you're too scared to do that, find a trusted parent or counselor to talk to about what you can do and what love is all about (most people misunderstood it). If you don't feel right or don't like him at all, then just ignore him (you can't force yourself to like someone, love is supposed to be your own decision) Hope I helped.
