It does and it doesn’t! I do understand what you mean about accepting those parts of our partners. But I don’t think all people desire that type of connection with more than one person. Reading this gave me the impression that you were saying that all people have the desire to connect with multiple people and I think that is too simplistic.
I definitely understand what you mean when you say it would be ignoring a part of yourself and\or your partner to ignore that desire for connection. I feel that too.
