Could he like me.. .. .. ..(Really long)?

So baisicaly i realy like this guy. And from september i would be..Staring :P Buh he was always looking back. And one day i was just walking by him and i didnt know he was there and i was just glancing around and he was fully watching me..Like the whole way out the door. But then he asked my friend for her number on bebo.. And she gave it to him but she said she didnt like him(And she has a boyfriend). And we were at my friends house and she was texting him and i go "Say hi" and she wrote"Eva says hey babe". And he replied "Hey y".. And another time we were messing and i was like"I loive him" and she text him saying "Eva said she loves yooh" :S And he text back"Is she joking?" Like i dont know if he likes me. Like we talk a good bit.. And up till the time he asked my friend for her number i thought he liked me. What would you say?? Xx
