I don't have a crystal ball. But my guess, and that's all it is,
is that this "cheating WITH you there", MIGHT delay but will ultimately trigger, the eventual break up of your m.
Enjoy your fantasy while it lasts. I hope I am wrong, despite how I feel about "open marriages" -
(actually I just don't see the point of open marriages, b/c if there's no commitment why bother pretending there is one?)
But please don't check off "Div Busting" as something you actually tried, ok? It's not fair to the program, b/c you never completed more than a weekend of behavior modifications, at best.
But regardless, good luck
