Thanks for all the advices,
I tried talking to him, but yes, as you had expected, he said he's
just not good with words... He's doing so little, that now, i feel
that even a phone call or a hug is good enough... this is not
right... calling and showing me affection (besides in bed, of
coz..) are the basics of a relationship... but these are the things
that seem so big now...
Is this what you call, "when you've been to hell, you learn to
appreciate earth?"
He is someone who thinks that meeting too often is not good, but
it's not that im sticky, i just miss him so much, you know the
feeling of loving someone and wanting to see him so bad? I don't
even dare to ask for a date, i'm afraid that he would find me too
sticky... but we're meeting just twice a week, no quantity, no
quality... He would be doing his stuff at home while i watch TV...
and when it's bedtime, he would come and hug me to sleep... i
cannot believe that i could feel so lonely even in his presence...
i'm so so so lonely...
I want to accept him, but i'm just too weak to do so...
I dun want to make him change into a person he is not, coz that's
not him anymore...
Actually i know what the best and perhaps, only option is---
Leave...
But sometimes, the mind and the heart just couldn't work in line...
Zhen de hao xin ku.... 
With thanks,
Vonderful.
