I think these words of mine are accretive to you message:

"Unconditional
love twixt humans forever?
Perhaps, perhaps not.
Love is a state of being.
Beings constantly in flux.

Diana’s prompt for today happens to be an oxymoronic “what are the conditions of unconditional love?” I suspect many have much to say on that topic. I have thought about people’s feelings on the subject and here is food for thought for you — love is a state of being — many feel one cannot fall out of true love — here’s the fallacy in that — many correctly believe that we are constantly changing — so, since love is a state of being, it is inconsistent to insist that one cannot fall out of true love. That one falls out of love does not mean the love was never true."

That tanka and explanation are from a piece I wrote a couple of years ago. It contains several other tanka on love. https://medium.com/know-thyself-heal-thyself/unconditional-love-3481bffe22f4

PS: My thoughts on detaching with love from a relationship are also germane and supportive of points you made here: https://medium.com/@marcus17043/when-should-one-detach-with-love-f63180af8c8d
