Hi, just need some advice and opinion. Thanks a lot if you can
help me out. 
I have a girlfriend who is now currently back in China. We met
while she was "visiting relatives" in Singapore (she's working in a
karaoke lounge to sideline for her family problems back home).
Initially, I was quite hesitant about such relationships due to the
bad image these girls get in Singapore. Actually, I know that she's
not with me because of money due to the fact that she doesn't want
me to visit her at the karaoke but meet her when she's free
instead. Also, she did not take any tips from me or in any other
ways. When I go out with her, she rather that I save the money on
taxis and is willing to take public transport with me instead
because she knows that I'm not a rich kid or anything like that. I
can feel that she's truly happy whenever she's with me.
In the meantime, our relationship continues in such a way that even
if I didn't meet up with her, she will call me up using her
handphone which costs a bomb for her. We would talk for long hours
on end everytime. I did mention to her that I liked her at the
start and she told me she has also liked me the time she saw me.
Her only apprehension is also because she was told that most
Singapore guys are only looking for fun at such outlets. It was
only when she was about to return home that we confessed our true
feelings for each other, that we actually do love each other. We
have told each other it is near impossible for us to be together
because of different family background and also different
culture.
Now that she's gone, I miss her a lot. She has called me twice
since even though she's gone less than a week and our conversations
were very long each time because she misses me very much. My
thinking is that if she's not true to me or serious about me, she
probably won't give a damn when she's gone, or even if she's
around. There's no need for her to waste money because I'd probably
just call her if I am serious anyway. Now I'm stuck because of my
inexperience with foreign girls, especially from China because of
their bad review. Anyone experienced enough to give me some tips or
help? Is she putting on an act because of money, for PR /
Citizenship or because she truly loves me? By the way, I'm 24 this
year and she's 22.
Thanks a lot.
