This is just to achieve their ethical poly standard. Less than that, you're half assing and not really poly.
I do wonder if this is partly why I have also seen such high praise, or pride taken in identification of "solo-poly." Solo poly is sought after - mainly because the rule of thumb is that it gives the least amount of institutional hierarchy.
It reminds me of that other thread, where you wrote: "Then, the single poly women are often looking for a 'primary,' which ironically entails many of the same things those poly married women want, just with the addition of marriage and kids."
It's something I've discussed with my wife. In that, I want her to make sure she knows she's available for separate vacations, with others, not me, etc.
I think in the end, while it's not something I have done, (I'm still only at 1 relationship, and probably will be considering my circumstances), I have certainly given it some mental exercise. And I wonder about the financial extension I would need to make.
edit: Also, I just want to say thanks, you usually provide provocative thinking posts.
