A few points:
I'm going into a triad/quad situation (long story, as always.) I'm having to move. Not my ideal, in that way, but I think the relationship is worth it. We met on OKCup!d, and were just friends for the longest time. Things ended up falling together a few months ago, and the rest is history.
Until then, I live within a few hours of you. :-D
Good luck finding your third. Or fourth, as the case may end up being. ;-)
