Sorry If I just re-iterated everything OP said, but I feel like you didn't entirely get the point of the post. A lot of newly polyamorous couples have no idea what they are doingand would probably appreciate the advice or guidance of someone who has navigated these waters before. Consider having one partner date people to find your ideal match if you are not willing to date separately. Couples spend a lot of time looking for the perfect partner. Couples that choose to date together artificially limit the space for conversations and intimacy. But if there are certain items that are permanently off your menu, let them know. Submit a new link.
I've often been jealous of unicorns, but after reading this, not so much.
It just seems ludicrously far fetched and complicated. Facebook gives you a more personal touch. I feel your frustration, even if it's not unicorny on my end. You might need some reminding that, should this not work out, there are other people out there for you. So there's a chance this couple will teach you some new, fun tricks.
