Lol, is this for real? Just out of curiosity, where are you, back home in Pakistan?
First, your FIL is a beta who needs to man up and control your MIL. Give her slap if required like my granddad would do to my narcissistic dhadhi. You are meant to respect and follow your parents in everything that is correct, not when they are wrong - try and get this through your husbands thick skull.
Second, your husband shouldn’t have gotten married if he was such a mamas boy. Why is he angry, he should feel lucky that you didn’t swear at him. Surely whats good for the gander is good for goose?
If I was you, I would ask for your god given right to separate abode, live separate from this Star Plus Kahani going on with your in-laws. What, are they uneducated or something? Trust me when I say this, your children will develop complexes later on in life from living in such an environment - I should know, I had to live with this crap up until my 22nd birthday when me and my oldest brother finally put my dad in a position to pick his wife and kids or pick his mother and divorce our mother. What is it with these Paki guys and their mamas, FFS!
