Lack of Compatibility is the main cause for divorcee..Which can be sorted out to an extended in love marriages...I mean ..when you are in love you know the person in and out..so if you cannot get along ..its over... no point in getting married.

But in arranged marriages you will find it only in the long run..then it will be too late for a divorce due to the so they carry on with the love-less marriage for the sake of the children/financial security or whateva reason (which is not common in the west)

Agree with Rami....what you have mentioned is a common scenario even these days..
