Should I tell my mother I'm narcissistic?
For context, we are not estranged but we probably should be. I have thought about cutting contact with her many times because she physically, sexually, and emotionally abused me throughout my upbringing. She and my grandmother are the only family members I still talk to at all, because I've already cut off my father's side (he was abusive too). I moved halfway across the world to try to get away from her, but she is still so entwined with my life that we call every week, if not more often. They are not pleasant calls, but I keep doing it anyway because...I don't know. I'm attached, I feel indebted, I don't know how to stop, she's my only family, etc. I think that if I tell her I am a narcissist, it may finally push one or both of us to cut off the relationship.
She demonizes narcissism heavily, and when I was a kid she constantly told me I must not grow up to be a "malignant narcissist" "like my father." Maybe she would just cut me off completely if I told her. Honestly though, I think she would just be delighted to have another reason to think of me as flawed and easy to control. She would probably start taking advantage of it as a reason why she can say or do anything she wants with regard to me, and would coddle me about it, with the intention of regaining closeness. Even then, I think that might be the push that I need to cut her off, because I am not letting her invade my life over this.
But I don't know if that's really why I'm doing it, or if it's even a good reason if true. I think a part of me feels dishonest in keeping it from her, because I know that she would want to know. I feel so guilty and I'm avoiding calling with her because I just have this weight at the back of my mind the whole time, of knowing something she doesn't know. More than guilt, it's a matter of wishing I could tell her and that her reaction would be an unexpected acceptance. Not false acceptance for the sake of manipulating me, but genuine acceptance of who I am with a desire to know and to help me. That will never happen, but I don't know how to give up on it. She can be so nice at times, and I have so little family left. It's difficult to stop hoping. If I told her and saw her reaction, that would probably kill some of the hope. It would also contain some element of proving to her how badly she has hurt me, which she only ever half acknowledges, if she acknowledges it at all.
But, I could also just end the relationship without telling her anything about being narcissistic, which I have wanted to do for years and years (maybe, if I can convince myself to do it). Or, I could let things continue as they are and keep it to myself, which is what I do with most of my medical information these days.
What do you think I should do?
