Im just starting to see him stare at me now. Do you think he has some crush on me, Im not really sure. Hes not really a dude who charms the How to Know If a Guy Likes · How to Tell When a Man Likes. The worst part is, some guys stare until I'm out of sight. It's so tacky, and it feels like they can really see me through my shirt! It's disgusting when they do that. Why would a guy stare at me all the time but not smile. He isn't frowning but he just has a blank look on his face. My friends have caught him staring at me a few.
