Toxic grandmother (hereafter known as TGM) and my lovely mum have just had huge row - TGM was carrying on in her usual racist, spiteful moaning way (you have to hear it to believe it, it's the most soul-destroying thing ever) and mum plucked up the courage to tell her that her attitude is why people don't phone her and want to be around her. Also that she was an abusive and lousy parent and is lucky that mum does anything for her.
TGM wouldn't have it. Also complained that grandchildren should ring more (this is about me). Is true I don't ring, but would you want to call someone who greeted the news of your first pregnancy and her first great-grandchild with OH NO and went on about what a disaster it was for ten mins (am 30 with lovely DH and good job, so this was in no way a cause for concern). She's always like this - told mum to abort every one of her three much-wanted children. I could go on.
She is a sociopath. But a sociopath of 91.
What do I do? I want to support my mum who isn't speaking to her. I don't especially want to speak to her myself. I know it's too late to retrain her.
But she won't last much longer and I also don't want to feel guilty when she goes.
I know what the right thing is really, I guess. But it makes me so depressed...
