She just complained about how she was going to get the snow plowed.
Isn't that all you really need to know? I think the hardest thing about coming to terms with this type of relationship is that you have to face the fact that
you didn't really exist--not as a separate consciousness with independent thoughts and needs, anyway. The narcissist, I think, views everybody and everything as an extension of his/herself, even in what are supposed to be life's most intimate and supportive relationships--parent/child and husband/wife. The "other" only exists as a support to, or extension of, the "self." If narcissists are really insecure (and I'm not always sure I buy that argument), then the "other" is really proof of existence: I manipulate, therefore I am.
Of course your soon-to-be-ex wife wants to maintain contact, because she wants to remind herself of how successfully she manipulated you, and therefore reinforced her idea of "self." If you really want to stick it to her, disengage. I have found with N's in my own life that the screaming argument doesn't really bother them; they always fight and often win. It's indifference that leaves them powerless. Remove yourself from the realm of things that she can influence, and watch her do her best to manipulate you back into that circle.
I often think that's the answer to the question, "How could I have been so blind?" You (or anyone) could have been so "blind" because a master manipulator put years of effort into blinding you! She saw something in you that really fed her sense of self, and she did everything she could to control you so she could have what you gave her. There probably were many moments--even months or years--when you seemed to be having a perfectly fine marriage (as long as you didn't actually
challenge her). Familiarity bred comfort, which in turn bred a sense of security.
I can't offer much concrete advice, but I am rooting for you. My brother had an absolutely disastrous marriage to a pure narcissist. He didn't know what hit him until 20 years and two children later. While he's divorced now, he is very bitter, and I don't know if he will ever really trust people again. Which is sad, because I remember him as a delightful young man--funny, handsome, intelligent, and decent. He was my hero when I was a little girl.
You're on the road to something much, much better than my brother got out of life. Please cultivate whatever it is in your character that let you start the journey.
I'm in the D.C. metro area, too. Isn't that first blast of summer absolutely intolerable? Every year at about this time, I resolve to move. Anywhere.
best,
