Tom, I hear what you are saying about jealousy and I have a definite opinion on that. It's also part of how we're brought up and goes hand in hand with my arguement about the 'one true love.'

Because we're brought up to believe in one true love, what if someone else gets to him/her first? Then we're left out in the cold, lost, and bereft of hope.

Zero-sum game strategy. You win means I lose. But that way of thinking, isn't the only games theory strategy. In life I try to play win-win strategies, and have found that when my winning doesn't mean you lose, jealousy goes away very quickly. When you practice win-win gamesmanship within your life, polyamoury quickly becomes not only preferable, but viable.


P.S. There is also tit-for-tat, (a favorite because I'm fond of tits)
