Divorce is bad for kids*, pretending it's a good thing for the kids is a flat out lie. It's a lie women tell themselves to block the guilt. What's more depressing is how much celebration there is around divorce, look at people congratulating her.
Regardless, it is good that women show men how frivolous they treat marriage. Men can adjust to the new social order that way.
*This shouldn't have to be mentioned, but someone will bring it up I'm sure. In some cases, like abuse, divorce would be a good option, but that isn't the case most often.
