Many have deep and lasting relationships with no cohabitation at all.
It would be unfortunately difficult to say which among these misunderstandings is the most common, or the most hurtful to polyamorous folks.
But there's one in particular that I'd like to discuss: the idea that "polyamory" means "committed couple who have casual partners on the side." There has been much talk about "open marriage" and "open relationships" in recent years, with some even paradoxically dubbing non-monogamy "the new monogamy." In this open-marriage conception of non-monogamous relationships, there is still a central, committed (often legally married) couple, who allow one another to engage in purely sexual (or at least quite casual) outside relationships.
Finding the people in our loves that touch us, enrich us and bring us closer to perfection isn't easy..it's worth the effort.
You can't just throw a bunch of elements together and call it chemist In 2007 I sold my house and most my stuff, and hit the road full time.
Generally, any discussion about the benefits of such practice revolves around how it strengthens and/or reinvigorates the central couple in question.
