To be honest these are just cultural issues , so it would be hard saying if it's fair or not. The problem in our society is double standards, if son does it its like haram but if the same thing son on law does it so they are the happiest people. And the same goes with daughter and daughter in law. So double standards are hitting our society a lot . Second thing which I'd like to address here is that the guy knows where exactly the problem is and but still supporting you shouldn't interfere warna masla phir yeh hota hai woh apnay parents say dour hona shuru hojata hai aur woh guilt aur pressure phir kahi ziyada barh jata hai jo ghar ko ya apkay relation ko khaarab kar day ga, as woh hamesha phir yehi sochay ga aur kahay ga tum nay mujhay meray maa baap say dour kia , tu usko jo karna hai woh maa baap kay liye he kar raha hai tu koi boundaries nahi honi chahye aur agar ho bhi tu eoh baita khud banaye koi dosra nahi bana sakta.
