What you wrote made me think, which I love, so thank you.
We are born one at a time for a reason. We come into this world flying solo, and we leave flying solo. To happily partner and travel through this life alongside another spectacular bird it’s important first to learn to spread our wings and propel through the air on our own.
You’ve got it going on. Do not waste one more precious second considering the motivation of that wandering one who blew your nest. Some relationships belong in the past so that we are free and prepared to experience what it means to indeed, soar.
