The one big problem that I have with PM is that it really means that you would be willing to divorce. If divorce is NOT an option, then the HD spouse has Little that they can do. I would love to see a book like PM for the Christian man if there could be such a thing.
As for the power, what real power does a HD person have? One of the reasons people become LD is to CONTROL the power in a relationship. The highest levels of vulnerability lie with people that are the Highest desire, and people with ND have virtually no vulnerabilty. They are the ones that completely control their own destiny. It seems to me that the only real power that HD people have is to divorce, its the only thing that we control.
