Hi Peach,
I can relate to this not because of Nmother (I did the Cinderella thing w/her for a decade until her death, good and bad...but she was not overtly abusive, just very maNipulative). But I am now NC forever with an abusive and pathological Nbrother, who slandered me viciously with incredible energy--even sending nasty material to elderly aunts and uncles, which scared them right out of my life too. That part was hard to forgive.
...its easy to say I shouldn't care, but its painful to have lost relationships and to know that I have been slandered for years. That I am seen as the "bad" "screwed up" one in the family.
I had to cut her out of my life, but the fallout is that I lost everyone who is connected to her.
Phamily is filling in those gaps. Fortunately for me, there wasn't a lot of contact in the first place. I love my nephews and niece but the truth is, don't particularly LIKE them (except one). I do miss knowing there's nuclear family for me somewhere, but PHamily (chosen community, in my case a UU church I am glued to, and real friends, including a few here) are golden. I am loved, and ultimately, I have been able to release the belief that it has to be bio-love to count.
But. When we do have to interact, or contact, or work with, severe Ns -- as PR says, they're behind every bush--what helps me, really very seriously, is when I gradually change my thinking to react to them as an animal. Not in the sense of "I am human and superior to this person who is only an animal". Not that way. But in the respectful way that I recognize that this particular species, while having its own unique strengths and beauty, is erratic and dangerous.
Makes one a bit of a lion tamer, but what I mean is--if I ever had to interact with my Nbrother again in future, I now know that he is literally a tiger. So, I would be mentally prepared with a strong fence between my self and him. (Do zookeepers let the tigers out on Tuesdays and Saturdays and keep them contained the other days?) I would regard his purring OR roaring as the unique sounds that this species makes. I would always be aware of where he was and never turn my back. I would recognize the crouch and twitch of tail as signs of a leap. I would never, ever, emotionally turn my back. For that matter, NC amounts to never entering the enclosure anyway. (In my case, if I had to, it would be accompanied by armed, trained keepers--as in attorneys.)
So even though he is a tiger, I can still be safe. Other Ns in my life are perhaps rhiNos or hyeNas, and some are only dangerous at times, and at other times diverting, temporary company.
The know-the-species thing helps me: 1) reduce my feelings of contempt, which sicken me, and 2) give me internal harmony.
I can still recognize their life, their value as human beings...while never forgetting which kind of animal they are to me. I am not a fleet beast, but I am a smart one.
So are you.
Sorry if this rambled around your topic but thank you for the thread.
Hops
