Crush but weird situation?

I like this guy but he doesn't like me. He always stares at me with his best friend. They always observe me. Whenever he is around he is never on his phone just looking at me and watching my behaviour. His friends talk to people sitting beside me but never with me. This guy and I text so he might have figured out that I like him coz I asked him too many questions. Everytime I cross road he stares at me from far away. Did I do anything wrong?
