Thanks for posting this article, I found it really interesting and related to a lot of it w.r.t. my own experience. I really loved what she said about having multiple marriages with the same spouse, and also this, oh wow:
Very often we donít go elsewhere because we are looking for another person. We go elsewhere because we are looking for another self. It isnít so much that we want to leave the person we are with as we want to leave the person we have become.
That really rang some bells with me!
Re: European practices, I can't speak for the whole continent, but the few polyamorous contacts I have communicate very openly with their partners about what they're doing (us included). The honestly and openness seems to be pretty important to them (to us, as well). I don't think I'd like a DADT policy for myself - I have a wild imagination that populates empty spaces with far worse fantasies than the reality could ever match! I much prefer things being open.
