And trust me this isn't just Pakistani culture, but something many Asian families practice. One of my best friends, a Sri Lankan, has faced this predicament many times. She is, by her own choice, a very religious woman and her parents keep wanting her to marry men who are totally non religious and so not her type.Some are even downright nasty and of bad character but are moneyed and having social standing for which reason her folks are keen. Likewise they have opposed many men she has liked(recommended for her by friends,etc). And many times they have subjected her to much emotional and even physical abuse. And I will do all I can to save her from them, simply because I know what they are asking of her, and doing to her, is very sinful and wrong! You cannot force your child to marry anyone he/she knows they don't want. It's criminal and even in a religious sense against a marriage contract.
So yes, if because of her staying home, my friend is being oppressed and abused, then I would help her escape.And then help her as much as I can.
