Thanks, PS. I think it's very possible that H has NPD & I am a co-dependent. My mother has NPD. The only relationships I've ever felt "passionate" about are with men who appear to have NPD - they lie, gaslight and engage in emotional abuse. My H has added "becomes physically threatening" to the list. Then if I do anything but ignore the abuse, such as respond verbally or get angry, I am labelled as the one with a problem.
I've begun to view H as "Bluebeard." You can have what he tells you you may have, but don't try to go in his "locked room."
Perhaps what I am feeling now is withdrawal. Realizing that we are ending feels like kicking some kind of physical habit.
