I have been thinking a lot about Blue Skies' objection to labeling someone as incapable of changing. Ever. And being outside of God's capacity to perform miracles (my words, not hers.)
And like so many have said: it's a probability game, and while I was waiting to see if my NPD/AXH would change, I was getting sicker, more in debt every day due to his insistence that we spend MY money and not his (plus, he was barely working) and my children were becoming more entrenched in our sicko relationship.
At my most detached, he left me and the children - because I had refused him his narcissistic supply - and he has not changed.
So it's not really a question of whether he can or will change, it's an issue of how much older you are going to be when Liz decides to start living again.
