Who would she talk to if it were not you? Is she actually playing the game or is she fantasizing about it? What would happen if you were not there to talk to? What would happen if you did not talk to her at all? Does she think you are playing the game with her? Does she think you are condoning her actions in this game and you are allowing an open marriage?
What would happen if you did not play the game?
Maybe going dark for a while would shake something loose.
I have no other opinion at this moment, but answer these questions and I will do some more thinking. NOT THAT I KNOW ANYTHING. Like you, I am here because my W walked out. And that certainly does not give me any more knowledge about these things. However, I would suggest you discuses this idea in detail again with your C.
