Apparently all those happy people aren't all that happy, are they?
The only 'happy' married people I know are the 20+ year ones--before all the 'sharing and equal' horsecrap.
If women wanted an 'equal partner', they would marry another dopey woman. They want a superior partner....
I take your word for it that the married people you know are unhappy, but that may not be her experience with the people she knows.
