Oh, Iphi and Debkor - there is so much wisdom in your words and I am grateful.
Deb, I think my very existence is a narcissistic injury to my NM. I am sure I do things unknowingly all the time to add to it. She rarely gets angry with me - just hangs up on me if I'm not in a "sunny" mood or cuts off contact, which she has now done. She's perfectly pleased if I eat dinner with her and watch a movie at her house. Or do things for her. But let it get any deeper than that and she's gone in a flash. Yeah, the people I know who repeated what she's said about me don't confront her or challenge her; she is too much of a paragon of society for them to do that. And it is exactly as you described - she creates a bad image of me in others' minds (or believes she is doing that) so that, if she offers me no help, she can justify her actions and not look bad. It's all about keeping up appearances for her.
Iphi, this is the first time I've heard about the Smear Campaigns of Ns and it sure makes sense. No, you are not speaking too boldly and I didn't find your words "astringent" at all. It's the truth. Thanks for telling me about the campaign. It gives a structure to what my gut was perceiving.
I wrote her a letter, but won't mail it. It made it real for me. I want nothing more to do with her or my brother. I am going to be OK eventually, and I never want to have to explain, justify, or defend my life again, certainly not to them. They have both turned their backs on me, so they do not deserve me. I have been good, kind, helpful, and loving to both of them, and this is what I get in return. No thanks.
When my brother got divorced the first time, he was broke and had no place to live. So I took him in for 2 years. As GS said (I think it was GS), his response in cutting off all communication with me is so immature as to be not worth discussing.
As to my mother's will ... I am removing myself - silently, irrevocably - from this "family". I believed when my NF died 2 years ago, there would be more stability in the FOO, but instead the insanity has been ratcheted up. If she leaves me in her will or if she removes me, so be it.
