I could give lots of examples but I dont want to. Id get lots of sympathy and horror but I no longer need the validation tbh.
I dont think the lack of interest makes her sad. I think the fact I won't allow her to abuse me anymore and make me doubt myself, and that I finally enforced boundaries with her makes her utterly furious tbh.
There is absolutely nothing she could do to redeem herself. I thought about it a lot - it wouldn't happen, but even if she had a personality transplant and was full of remorse and wanted to atone, she simply couldn't. I would never be able to forgive, and I would forever be wary that the rug would be pulled at any point. She is a very dangerous person, and I wouldn't be able to allow her access to me for risk of her causing further harm.
I do admit IRL that I can't have her in my life, and I won't ever forgive her - what I don't admit is that I don't love her or miss her and I prefer it this way now. That, I think, is too hard for a mother to admit out loud. If it wasn't happening to me, I may have judged myself.
