So Interesting!
Oddly, I am someone who tends to want to hold onto relationships more, and longer, but somehow this paragraph resonated with me as a poly person, but in a different way.
Currently I only have one partner, and consider myself polysaturated. However, I still consider myself poly, but it feels almost like a need I have.
Many times I have sat my partner down, and told her that I don't want her to be with me because of a sense of obligation. I make it clear to her she is free to leave whenever she wants. We also have a child tighter. But the idea of her staying with me for security, or commitment and not because she actually wants to be with me, feels so awful to me. I am no one's obligation, people who are with me are with me because they want to be. I definitely don't want a partner who is with me for any reason other than they truly want me. It does feel like deep down this is connected to my polyamorous spirit-and I feel like you touched upon it here.
