I do agree with MAGDADELA to a great degree. By nature love marriages are just another eposide in most of the romatic relationships hugely motivated by (or built upon)sweet fantacies (or the desires of such) with very high expectations of realizing those fantacies. When those expections are not met the marriage itself cannot bear the burnt of such dissapointments. Divorce usally becomes the means to console such dissapointment. Arranged marriage usually does not begin with huge expectations in the first place so there is a much greater chances that the dissapointment will be fairly low therefore there is a far greater odds that it will survive the bumpy rides along the way.
