I love the word interdependent. I have used it to describe a healthy romantic relationship: "each partner should maintain their sense of self; no one should lose who they are to the relationship; it should be a partnership wherein each person maintains their autonomy; kind of like a treaty between, for example, the United States and Canada — contributions and rules are agreed to but each country maintains its sovereignty;" and the ideal relationship between human (Greg, my birth name) and our souls (Marcus): "integration is supposed to be a state of seamless interdependence — Greg cannot nor should lose himself to us — we should exist in harmonious symbiosis — we should each be aware of the other and of our separate completeness — almost like a re-united split-soul [at the time I believed in the twin flame myth]— the only thought that existed of this before we just wrote it was one word –interdependence." Those quotes are also in my 2020 self portrait that I linked in another response
