Hi Nantucket,
That is a question I am also asking myself.
The reason I wonder is to know if there is ever any hope of having a genuine friendship with my ex going forward. If he really changed deep down inside and was able to be accountable for the harm he caused by being closeted, would I be at peace?
I know I have to get to that place of peace unrelated to him and anything he does. And I've been feeling more and more peaceful. But sometimes the hurt and anger rear their ugly heads, and the doubt (irrational, I know) that this was somehow "all my fault".
There's a book: It's Not You, by Ramani Durvasula, about narcissistic people. It was a true balm for my soul. She says they'll never change, but this is general narcissistic tendencies, not someone who had to act in a self-protective way because they were hiding their true self.
