So, if the husband refuses to move out when the means are there, and the parents are able, then i think that is more of a general reflection of insecurity on his part, rather than the wife's and the affliction is well known as 'mama's boy'!
We know that in Islam our parents are to be respected and cared for, but no other muslim culture goes as far as South Asian in so clearly defining how that care is to occur. Why does the culture put so much emphasis on binding only the son to his parents? Is it because this is the only interpersonal relationship that provides security to a woman?
Good points! :)
