DECLARATION FOR MISTRESSES : Career as a Priority

"My first priority is education and the development of my career, for only the  privileged and lucky are supported from birth to death by someone else.  Most women spend a lot of time single or as single mothers!  How great it is to have it all!  How few do!"

MISSY ASKS YOU : YOUR RELATIONSHIP IS BUSINESS BUT HIS MARRIAGE ?

The career couple - his and her - like Bill and Hillary Clinton (though we have yet to hear that Bill or Hillary ever kept a woman) - often accommodate affairs and mistresses. Marriages like the Clinton's are often thought to be just for mutual career advancement or politics.

Mistresses are often thought to be just part of business.
But his wife? She isn't staying in "just for business" or is she ?
What about the prestige of the couple within their community, such as at their temple or church, or his reputation in business founded on the idea that he's a strong family man?

Who is most motivated to keep a husband, a wife, or a mistress?
