Families are MUCH closer in Pakistan and the rest of the Middle East than they are in the western world. Doing things against the families will can get you in big trouble and leave you without your family at all.
The main difference between the Middle East and the West is: in the west, you grow up and you are taught by your parents how to stay on your own. That is why Westerners often only see their parents and brothers and sisters occasionally. In the Middle East, you grow up to be a good part of the family for the rest of your life.
As I married a girl from the Middle East I had to learn and feel the differences and resulting occasional tensions. So to say it short: you normally are not supposed to leave your family in Pakistan. So this girl feels she is in great trouble, even if the solution may seem so simple for us.
