But wait, did you know there's another choice? LAT. Living-Apart-Together.
Everyone probably knows that living together before marriage is supposed to increase your chances of marrying someone sufficiently compatible with you.
LAT is on the flip-side of it. It can prolong your marriage beyond a point where divorce might have been the only option given the insufficient compatibility between the couple.
My suggestion is no one should consider divorce before trying LAT. And lest you believe it's a brand new western concept, gentle reader look eastwards, towards India, the land of the kama sutra. There you will find the time honored tradition of the wife retreating to her mayke or puttillu - for a temporary separation (LAT) supervised by her parents.
It has worked wonders for marriages in India.
