As a marriage Counsellor I've personally found that most cases of cracks in marriages is due to lack of skills of relationship management among the spouses. This culture of bride preparation allowed elderly women to teach the bride to be those skills they need to build their homes and create lasting peace and harmony. In those days, divorce rates were very low. But nowadays, the average lady goes into marriage with just her beauty, often along with ego and wrong stereotypes learned from social media. And their relationships break up with the slightest strain. Let go to your blog and read about your culture. It's fun learning these things.
