"His perception of drama was me, trying to hold on to myself."
^^This!!^^ Frrrreeeeedddddooooommmm!!! Better than freedom from him, you have found the freedom to be yourself again. Congratulations to you, Expanding!
Now, do yourself a favor and print your post, or screenshot it, or do something to make it easy to access. Because as you know, grief cycles. You will find yourself in those moments again when you don't want to be strong. And you'll get the amnesia that comes with missing a partner or your past or the fantasy of what could have been. When that happens, open up your post and re-read, and re-read, and re-read.
You get to be yourself again! Enjoy you!
