Do u think he has stopped liking me now or he still does?

This guy likes me and looks at me quick then looks away and he looks down when i look at him while he walks. when I sat oppo him he figeted like mad and kept looking at me subtly. He turns his volume down on his music/laptop headphones when I am talking alot I know as when I tapped him he turn round and said sorry and I was like thats alright but when I'm talking alot and shouted at him he turnt round so I knew he had it little lower so he could hear me as it was only me him and one friend of mine in cl. He tends to isolate him self on his laptop which his music, but hes gradually sittitng closer, I don't know if he likes me though as when it was the 3 of us in cl I was talking about people and how I know when they lie and how I can read people SO if u were a kind of shy guy who liked a girl who has quite a few guy friends more than girls and u liked her would u be intimidated or feel..nervous or something I am not sure - what do u think Also I'm 17 hes 20 - does he like me, what do u think and would u not like me because. :/
