Hey there pegausdream,
Welcome to our forum.
I think you'll find yourself in good company here, as there's all stripes of polyamorous people here. Have a look around at our various threads, and post if you have any thoughts or questions. As for polyamory per se, I agree that it is something of a life philosophy, with a pronounced emotional element.
Glad you could join us; I hope you'll enjoy your time here. You sound like a positive and exciting couple.
Love means never having to say, "Put down that meat cleaver!"
