Does he like me?

Ok so there is this guy I have liked for like 2 years and he's sweet and he lets me lay my head on his shoulder on the bus when he knows I'm tired after a long day and when I'm upset he asks until he finds out what's wrong then fixes it by making me laugh and telling me I'm very pretty blush anyway I am SUPER clueless and I need help plz!! I have no idea if he likes me and if he does how do I get him to tell me
