Have you maybe talked to more men than women about it?
I actually did a count of the divorced people I know. And women wronged to men wronged comes up almost equal, with women wronged slightly ahead. And some of the spouses who were the culprits, were family and friends.
About the same but I examine the circumstances in each case. A guy who's not been shafted will claim to be shafted and a women whose ex-husband was shafted will never admit that he was shafted. (and in those rare occasions vice versa)
