Any solution to this common poblem?

So our culture can’t be wrong? There was a time when slavery was acceptable in many cultures that doesnt mean we need to stick to it. Racism was a norm too back in the day but now its considered unacceptable.
We need to move ahead in a positive direction, not stuck in a hell hole of inlaws and crazy idea of everyone living “happily” together which almost never happens in real life for the vast majority of joint families. Theres a reason why we keep hearing of saas-bahu or devrani-jhetani- nand fights all the time.
It ticks me off only because when im marrying someone, i want to have my independ life with that person where i can make my own decision whether its somethign as minor as the curtain selection or decisions regardin my children.
I don’t have a “right” over my kids decision once they are mature enough to have thier own jobs, live on their own and get married. ONce you get married, its you and your spouse who should be running thier households.
