What kind of signals is he giving? Is his body language different to how it was before? If you feel comfortable around him, maybe ask him =) Do you like him back?
Well when were down the sk8 park, he talks to me and he is always flirting, but when were at school he avoids me coz i dnt get along with some of his mates, but his best friend told me that he thinks he likes me
theres ment to be loads of ways to tell if a guy like you, like if his feet face towards you but you'd look abit daft if you look at his feet maybe see if he want to do something together like the cinema or something your both like and maybe start talking to those friend you don't get along with to well
i was like that with one of ex's mates but we may of said dtuff but it was in joking way maybe if you explain to the lad you like its not huge you don't hate each other but just wind one another up he might seem to talk to you more at school
Get him alone and ask him in a frank manner whether he'd like to receive a Cleveland Steamer with Reverse Teabag dismount. If he hastily jumps to his feet grinning like a Cheshire cat and starts laying down the tarpaulin, then you're in my friend, you're in!
