there's only so much a girl can do once she is in pakistan surrounded by relatives, her passport etc confiscated by the parents and no permission to go out or use the phone. i feel for girls who have to go thru such harrowing experience at the hands of their own parents!!!
i have heard that some of these gilrs, when they get back to states/uk or which ever western country they r resident of, approach the authorities there and try getting out of such marriages as they feel protected in these countries due to better law enforcement etc.
if this is what this girl went thru, then i would suggest she shd try to reassess the situation and see whether her marriage is workable or not. if not, then she shd try getting a divorce and move on with her life.
