I have been looking into polyamory lately. With today's world, I think it might keep me from feeling rejected as often as I do.
Interesting.  Being polyamorous does not imply that you are not seeking a deep and long-term relationship.  It only means that sexual and relational exclusivity are not necessary for it.
I agree! I think people tend to look at polyamory as a sign that someone can't commit to another person, but it's totally the opposite.
Another important component is that all of your partners are okay with polyamory.
Of course. Communication is important in a polyamorous relationship just as it is in a monogamous one. Are polyamorous people generally happy?
They typically include components of love, intimacy, honesty, integrity, equality, communication and commitment, so I would think so!
Seems like it would be pretty difficult to find other people okay with it. Are polyamorous relationships rare?
I'm not sure.  The word verified appearance of the word was in May 1992, when the Usenet newsgroup "alt.polyamory" was created, so it's been around for a while.
I guess so, but 1992 still feels relatively new for me, in terms of how long something's been around. I'm older than the term is.
I'm older than that as well, and I'd never considered polyamory!
