thank you to those who recommeneded it. Just read i this morning and its amazing. Its almost like reading a story on my life or something. Her behaviour is there, in black and white and i couldnt help but just be amazed as some of her stock responses etc are there too.
AM going to pass it onto sister for her to read.
Sister is seeing her today. Ive told her that she can talk to mum and say ive asked her to ask mum if we ( DD and i) can go round. But that i will not discuss nor agrue nor mention the incident.
I have had many confrontation with her to know that it falls on deaf ears - or that no improvments will happen.
What i am going to do, without telling mum what im doing. Is to refine a new relationship with her. It will be a pulled away one, but i now know from reading that book how to respond. or non respond.
Ill probably pop round one day next week. If she tries to bring anything up, or make comments, im just going to say ' im not going to talk about that' and if she does it more than twice i shall say ' i told you, im not going to talk abou that, im going to leave but ill call you in a few days'
I suspect its going to be along and rocky road and mum will hate it. But its just tough.
so - thanks to those who recommended it.
