My wife and I are actively polyamorous, but just barely. We've gone through one situation and are easing into others, with the caveat that it may not work in the end (if anyone has any advice on this, I'm all ears).
In the meantime, I'm a pretty emotionally-connected individual and love sinking into people even if I don't plan to have a physical or long-term relationship with them. And, I've fallen for a person or two that I haven't started a physical relationship with, but with whom they and I have shared intimate moments, thoughts, and confessions of attraction, each time, I've told my wife about them (though not without some difficulty. . .funny how getting your mind around something new can be so difficult).
One of them is married and herself wondering about other relationships, and she and I have had several lovely conversations, but have also agreed that, though attracted, we wouldn't do anything physical b/c of the honesty question, and she hadn't figured out how to chat with her partner about it, and, even though they have come clean on much of it, they aren't interested right now (as a couple) in the concept.
So, when you meet people who you are attracted to and visa versa but who don't move in poly circles, what do you do? Hang it up? Bring them into this interestingly fantastic world? Keep distance? etc? It doesn't help that both of them are friends and creative partners of mine.
Ah, attraction, such a wonderful part of our makeup. .
