Does he like me ?

i quite close to a guy recently . he was my fren for 3 yrs but we didnt really talk to each other . my frens tell me that whenever i am around . he will look at me . but this is before we talked . now when we are close . he would do anything i request . lyk : going to study with me , take my bag and a alot of other things . we spend hours in msn together and we also talk on the phone every night . its becoming our habit to talk to each other . i don't know if he treat me as a normal friend or he likes me . he don't treat other girls like this . when i am sad , he will try his best to make me smile . when i am angry with him , he will bomb me wif lots of sorry . wad does this mean ?
