Bro, great story, thanks for the update!
Pretty sad indeed, that you gotten that far, but I guess you are right.
Its going to be really tough for a girl to accept a man who is married, even if she's in love with you, especially for a 21yr old girl who is actually attached.
Complicated stuffs you got there.
But really glad for you that you are still friends with her till today. I personally believe that finding a girl that you like is easy, but finding a friend who stick with you is so much more difficult. I hope she's that kind of friend for you.
Jiayou on the updates! Like I say, will be camping here and rooting for you!
