Right, that's what I meant. I wrote in haste. "Fidelity only within the group" sounds like it could encompass infidelity outside the group, but no, we're talking about the same thing: monogamous marriage but with three people instead of two. I still think I like "equilateral triad" better than "poly-fi" because of the Marine thing, but it's good to know where I fit in the vast heap of new terminology that the poly community, which I guess I'm part of now, seems to have generated.
