Dear Beth,
No, I don't try to second guess an N
With my nmom, three years ago, she knew that I was becoming more aware through my researching and reading, and so she set a trap for me, then enjoyed herself; my expression of surprise. My nmom has other disordered traits and is very very, scarily, clever.
With my ndad, now he is different, last year I believed in good faith a story he told me, until, my inner self told me different, so I contacted the third party and during my conversation I mentioned my ndad's story account, to which it was then confirmed, that he had lied.
So, with the true facts, I was able to approach my ndad and remove his mask. He was in shock, and he did not like to have to admit, amazingly, he did admit, but, however, he did a quick shuffle with some blameshifting etc., and, he never apologized to me.
Assuming as they taught me in my DV support and advocacy training, only makes an ass out of me! Which I really like to retain

Hope my true life story accounts are of some help.
Love, Leah
