Is neither here nor there,men would also divorce women,if the percentage is higher in women then it's because women are more emotional
Well for starters I think it has to do with the fact that women no longer accept and go ahead with the traditional beliefs that you have to sit back and deal with whatever your husband dishes out, be it infidelity or abuse. Women have become more self aware of their value and importance as wives and as partners where as men still expect women to deal with all their issues, whether they're cheating or being abusive.
On the other hand, men generally don't file for divorces because these days we've become the more tolerant of the two sexes and we're usually the perpetrators of most of the things that make people get divorced in the first place.
As far as I can tell, the increase in divorce rates has very little to do with the increasing success rates of women, instead, the success rates of women is increasing because women have decided to step up and not be confined by societal constraints.
I hope this helps.
