why doesnt he chat to me!!?

[Indio Hilton]

ok so im getting to know this guy, i met him in a bar, saw him a few times before finally chatting to him, now the past 3 saturdays out ive seen him. he lives in reading i live in london soooo the is already a distance problem there. but hes invited me and my friend to come see him in reading next weekend, infact he mentioned it ALOT! the last thing he said to me on sat night was come to reading!!

were also facebook friends. i added him, but he accepted instantly, we chatted that night on there for a lil bit after id originally said hi but then i had to go. hes in a band so he has like almost 2000 facebook friends, but he said to me on sat, i have so many facebook friends i dont know half of them, unlike us, were now friends, and gave a cheeky grin.

but he never says hi to me on facebook, even if were both online for like half hour, he doesnt say anything, and i dont wanna seem overly keen by saying HI everytime he pops online! he hasnt mentioned me going to reading since, so i dont wanna bring it up incase he thinks im crazy haha i dunno what to do!! should i say hi when hes online, if i liked me so much why wouldnt he talk to me?
