what should I do?

ok so I know this guy from school but we never really talk…so now that school is over I sended him a message saying what’s up..so we kept talking..I told him that is pretty cool that we’re actually talking and he said that it was cool that we get to know each other..he has asked me how many siblings I have and stuff like that to get to know me..at a point I told him I dont usually use wink faces wich we have been using a lot that he’s the first person that I send a wink face wich is true…the same day on myspace (all this happend on myspace) on his mood.status it said: does she? and a wink face so I think he was talking about me..specially because we talked like for 4 days all day to each other..anyways he had like 3 days without getting online(for me like years wich I havent sleep wondering why) then he told me that his grandma had a heart attack and he spend couple of day at the hospital that explains why…but after that he gets online like 5 minutes a day because hes at the hp with his grandma and like its all we have talk about but we have talk very few..and im trying to cheer him up telling him that its gonna be alright and sending him smily faces but I dont feel that back from him is like he’s sending me cold notes now…should I just live him alone or try to cheer thim up a little or what??
