A recent study showed that 80% of the time, the wife in the marriage files for divorce. That surprised me. I knew that women were more likely to file for either an contested or an uncontested divorce, but I didn't expect it to be that lopsided.
There are several theories as to why that is. One is that marriage is still a tenderized institution. That means that even in our enlightened times, gender roles are still very traditional. the woman is often still responsible for the upkeep of the home and child raising.
Another theory is that women are just more tuned in to relationships. They notice that something is wrong well ahead of the man. In fact, it's not unusual for the man to be taken by surprise when she tells him that she wants a divorce. By the time she says those words, she's already made her decision.
