Update: she has to work on the family farm and also look after her parents so all I can do is be a good friend and visit her next year. She recently got I Jared when a car crashed into her motorbike so she can't even work. Life can be very hard for some people. I offered to pay for her bike to be repaired so she can get out once she has recovered, but she refused any financial help.
So not all asians are just after our western money. As for a long term relationship it can happen, but in a very restrained way.
