Many men do not appreciate they are victims. Those who are ‘purchased’ and ‘owned’ will eventually realise what they are.
Those who think they ‘wear the pants’ find out those pants don’t exist.
Unattractive men who have some property are the target. They aren’t rich enough to think the female is a gold digger, but have more than she does. Usually his lure is a house.
If she can not get her name on the house, the marriage ends. For he is not who is being married, it is the house.
In some cases, it may be a business or a connection that the wife can use.
It is after she gets what she wants and leaves, if he investigates, he will learn how little he meant to her, and how much contempt she had for him.
