Girl's Behavior

Does a guy like you if he changes his appearance/behavior?

This guy has been giving me mixed signals since the beginning of the school year. This past week though I've noticed that this guy stopped wearing his glasses, got a haircut and is wearing better outfits. As well he has now been passing by more often where I eat lunch with my friends (3 times now) and he walks really slow too. He doesn't talk to me unless were with mutual friends and takes notices of me when I enter the classroom.

Does he like me?
