You could be married 35 years and one morning he wakes up and sends you home.
There’s no security and it hurts. Imagine going back home after being married for so long,building a life and so on.
We need protection

I don’t know why our society accepts talaq that’s casual and petty. Talaq is not meant to be a power flex. Shouldn’t all those years of marriage mean something? Is it so bad that one “mistake” cannot be resolved without resorting to divorce?

In other Muslim territories talaq is serious, but here it’s largely dependent on the conscience and humanity of your husband.
You leave an entire life with nothing. It is absolutely unfair

Then society scorns you for being a bazawara, a failure and a cautionary tale for women. Your feelings are not important because it is always your fault that he sent you away.
Watch how they will say this woman deserved it because she danced for her husband.

An arrangement that allows a man to decide your fate based on his mood is not a good idea.
