Detaching with love can be very hard to do. Sounds like that soulmate prepared you for one that may come next. Also reminds me of this poem I wrote a couple of years ago in response to a prompt about the conditions of unconditional love.

"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."

I had a few more poems in the piece if you're interested https://medium.com/know-thyself-heal-thyself/unconditional-love-3481bffe22f4
