'monogamy mind-set' expects/allows primary r'ships to be changed 'poly mind-set' doesn't.So, I really have no idea what you mean by tha last statement
I also seem to be un-hip to what that last was supposed to mean. Poly mindsets can allow for primary partners to change, and for those of us who don't wait until we're married to be poly, there is no reason why changing of primaries would not be an option.
