The previous generation was too concerned about society & would continue to live through unhappy marriages. The present generation is less tolerant of the same. So 10-15 years back the same numbers would have had an unhappy living. These people probably are relieved after the divorce. Of course there would be some stupid people who do it in a haste, for whom counselling etc is reqd, but then there are lot of genuinely unhappy couples who go on to lead happy lives after divorce. It doesn't make divorce a good thing, but then in life there are maany painful decisions you have to take for your own betterment
