A young g/.f of mine is facing similar problems.
Her fiance is japanese. She is Singaporean.
She is close to her family members in sg, and really dont want
to leave.
Her main problem is actually finaces. Her future hubby has
not really talk with her about how he is going to provide for her
in Japan.
And her concern is whether there may be enough allowances
for her to send $$$ home for her parents while she is away in
Japan.
She felt that her hub is too stingy and may not help her
parents. And for her to quit her job, cut off her earning
power and relying on her hub.
In chinese, she kinda dont want to see his face to lead her
life. And she have not got assurance that he is willing
to bear her burden.
