Thank you for your contribution Lilslave :)
You are absolutely correct on all of your points imo/e. Poly isn't for everyone. Most people need to be and feel they are the only one for those they Love. Yet even in Poly, that is still true in it's own way. No two people are exactly the same, no matter how similar they may be, or what the in commons are. Each person is special and unique unto themselves. No one is replacable.
Every Relationship is also different, even with the same person. Like people, each Relationship is special and unique unto itself also. No two are exactly the same, no matter the similarities.
So for people who are, or are open to Poly, it works for them. Or can.
Very true also, that jealousy can get in the way of success in Poly, like in any other Style of relating. And even more so, because there is not just a one on one component to those Relationship(s). Though that component also exists (one on one relating that is). Working together to overcome or resolve jealousy issues is very important, as unresolved jealousy is kind of like a virus, or a disease. It increases/multiplies over time if left unchecked/unresolved. And yes it can destroy the Relationship(s) one hopes to build.
IME, everyone has triggers to jealousy. Care must be taken to recognize those and resolve them if they occur.
Compersion can also be blocked if jealousy issues remain. Without compersion, it is difficult if not impossible, for Poly Relationship(s) to Grow and develop normally. Normally for Poly Relationship(s) that is.
Honest Open Communication between all parties to Poly Style Relationship(s) is very much the key to their success, just as in any other Style of Relating. And again more so, because of the amount of people involved.
As you have discovered, it's important for each person to have their own place within the Relationship(s), as well as their place within the Family, when it's a Livein together situation. I found out the hard way (unfortunantly) years ago, it won't work out otherwise.
As you've also mentioned, it does take Time and lots of communication as well as negotiation between all parties, to determine whether or not a Relationship is a viable option for all of them. So just jumping in and hoping things will work, rarely does. Though sometimes people do that, and then have to suffer the pains of defeat or failure. When Time and communication could have prevented the problems altogether. Sometimes a person, or people, just want something/someone so badly, they fail to recognize the red flags, and they make this mistake, or mis-take. I've BTDT, and I don't plan to go back there.
Congradulations on your Family Lilslave :), and Blessings to you all.
Thank you again for your input.
