Well, you were given a chance then but you did not grab it...
that's life.
Frankly, if your 'he' jiemei did pop the question for you, would
you consider ? ... that's the question to think about.
While on his side of thinking, he had been wanting for you and yet
you didn't give any respond. Maybe he thought that you know his
feeling and the time given for you is already long enough.
P.S sometimes, a guy cannot have close gal friend
when he is attached.
Cheer up
