My mum is a complicated and often difficult person. I'm increasingly wondering whether she has BPD or a covert narcissistic personality disorder. She certainly seems to display a lot of the traits.
My relationship with her is slowly breaking apart. This is a source of intense pain and sadness for me but I can't continue to tolerate her unprovoked, controlling and manipulative emotional outbursts anymore.
I have two young children. My mum is particularly attached to my daughter, who's just turned four. Mum is frequently starting to use her love for my daughter as a way of guilt-tripping me during her outbursts, and has used almost litigious language to describe the situation. For example, she's talked of me "withdrawing access" during a period of time when mum and I were not on speaking terms.
I feel deeply uncomfortable with mum continuing to enjoy a close relationship with my children while our own is in such a mess. More importantly, multiple red flags go up when she talks about my children when she's having an episode - she is very possessive of them, and clearly struggles with the idea that other relatives might also be close with them. I think she sincerely believes that, as the maternal grandmother, she is at the top of a hierarchy.
What is reasonable here? I've been taking the line that if she can't respect my boundaries, I dont want her in my family space. A few of those close to me have seemed surprised at how hardline I'm being, suggesting that I'm being overly harsh.
Has anyone been in a simular situation? I really need some help working out for myself what best protects my children and myself.
