I have made no predictions of the certainty of outcomes. I did preface my thoughts with a "perhaps". It is right there.
However, bravo for supporting my usual position. Running away seems to have worked, as your Ex was not ready to change. And you were. Glad he is out of your life.
Perhaps your ex will eventually grow and figure out what he's doing is unhealthy for his favorite person: Him. And then maybe he'll set out on a course of real change. Perhaps not.
