So I'll try to keep this concise, sorry it's a saga!
Ever since I got married, years ago, my relationship with my parents, especially my mum, has degraded. We went from being very close, to her just never being interested in spending time with me, or ever reaching out to know how I'm doing. I tried to persist to keep things going, but the continual rejection and indifference really wore me down. Even when I had kids, she wasn't interested in being particularly involved. My dad has always been fairly ambivalent towards me, but me and my mum were very close before, which made the change really hurtful to me.
Over the last year, I've come to see that my mum has mental health issues, and shows serious signs of being a narcissist. There have been serious issues amongst family members, and mum has always tried to paint herself as the victim, tried to get me 'on her side'... Her determination not to take any responsibility has even gone as far as her accusing my sister and BIL of lying about her and sabotaging her, and even accusing my DH of stabbing her in the back and lying.
After a year of emotional manipulation and frustration, I decided to go NC with her and my dad, as he is completely blind to her behaviour and constantly enables her, and joins her in blaming everyone else. Her response to a sincere and heartfelt email from me explaining my decision and reasons, was a bullet point list of why none of it is her fault, why she has it worse than anyone and why I have no right to criticise anything she has said or done, or any right to be upset.
A third party has just told me that for certain reasons, she may soon try to get in touch with me to make peace. Now, if she does so, she stands to gain something personally important to her. So I know it could be she just says the right words out of pure self-interest. And I really don't like the idea of how much she'll resent me if I stand in the way of her getting the thing she wants. Plus there is always a part of me that hopes she will see the light and actually try to make amends. But I really don't want to get dragged back in after everything I went through to get away from them both and all the pain and drama she caused, and my dad enabled.
Added to it all is that they haven't even met my newborn, and don't know where I live, as I got pregnant and we moved house just after everything really kicked off about a year ago. It's made me feel like a terrible person, but bear in mind that if they'd ever actually contacted me in that year and asked how I was, I would have told them about the pregnancy. That is literally how little they care. And them not knowing where I live has actually made me feel safer. I feel really anxious about letting them into my kids' lives again, and them knowing where they can track me down, if things go very sour again...
So assuming she does reach out to me, would I be unreasonable to give her the benefit of the doubt?
YABU- don't trust her/narcissists don't change
YANBU- give her a chance
