Sounds like love.
"I hesitate to put *any* label on this."
Heh, that's why I did it for you.
"Is it best to just see what happens here?"
Oh I suppose. Not that you can't be proactive about things, but, no need to stop the relationship from developing naturally (sez I).
Other than the (moderate) long-distance factor, I think the three of you have come across a sweet deal with one another. My vote is to smile and enjoy the ride.
You mentioned that your hubby is rather traditional/conservative. Is he okay with the poly aspect of this situation? (If he is, that's one less thing, y'know?)
Do you think the three of you might move in together eventually? I probably shouldn't ask so early in the triad relationship, but I was curious.
What about your friends, will you tell them? Do you anticipate any repercussions if you do?
Ah, don't be too nervous. I think the emotional forecast is Sunny. Not that love isn't a risk; true love always is. But what shall we do? forgo love to avoid the risk? Nah; that's no good. If you love someone, love them for as long as you can, and set them free if/when they need it. No need to regret having loved and lost; it's a good decision on many levels.
What sort of reading/posting have you done here on Polyamory.com so far? What's been the most helpful?
Rooting for you,
