I get what you are saying and it is a problem in most western countries. However, it is very different what our society expects from women. It’s hardly about seeking instant gratification when it comes down to dreading waking up every morning to abusive husband. Our society and even families expect us to sacrifice everything we have and we are for the sake of their honor and relationship stability. How stable is a marriage where the wife and her kids are constantly being abused?
Another problem is the very men these women marry DO NOT understand what abuse is. So to stay in an abusive marriage means throwing your life away for absolutely nothing! They gain nothing but lose a lot! It’s one thing where a man is being abusive and he knows it but it’s an entirely different issue and very difficult to deal with when your own community doesn’t understand what abuse is and expects you to put up with it.
