What is a little ironic about this thread is that as far as I can tell, SGB is not in a "relationship" at all!
Some clarity needed: an "Open Relationship" surely means that you have committed to someone and see them regularly, or live with them, or are married. If the relationship is "open" that means you ( both?) have other sexual partners, and have agreed this.
The other lifestyle option - non-monogamous- is that you are a single person, you live alone, and you have a series of sexual partners, either single or multiple, with no greater commitment or attachment to any one more than any other.
Women have made these choices for decades. They are not simple repressed creatures who need rescuing from some cult which propels them into marriage.
What I find offensive about the arguments here- especially those of SGB is that a) you side step many questions and points made ( such as my pointing out that there are women bankers, lawyers, CEOs, drs, you name it, who are not supporting a man by being a domestic servant- sometimes the men support them) and b) that you criticise monogamy in a way that would be highly offensive if the tables were turned on you- and people criticised you for living the life you do.
I and other people may pick holes in your arguments, but as far as i can see, no one has criticised your intelligence, or you naivity for having the life you do- whereas you do that all the time to people who choose a different type of life.
You take someone's personal preferences and then extrapolate huge political, sociological and anthropological theories from that. These don't hold water , which is evident from the way you keep trotting out the same points even when asked specific questions, and there is no real evidence for the points you make.
Rather than simply saying "Do what makes you happy" to the OP, the discussion takes on a very nasty, patronising tone by belittling other women who think and feel differently.
