As far as my knowledge goes they tend to get more physical, find excuses to touch you, hug you, tickle you ecetera. Although, your question is difficult. It really depends on the guy, his age his personality, if he's shy he might seem more reserved around you or he might get a little awkward when he sees you. see if you can either get friends to notice if he's checking you out when your not looking, or if you can catch him your self, alot of guys can be sexist and old fashioned, but if he's worth it try not to scare him away by talking too much or, smiling at him every time he looks your way. He may be digging you, but when you like him more than he likes you it gets kind of creepy.
