My wife and I have been married over 20 years. We have two autistic young adult children, and she has borderline personality disorder.
Due to BPD, my wife has abused the children emotionally in many ways, threatening suicide, blaming her drinking on them, insulting them, preventing them from speaking and acting independently. I have remained with my wife to protect them, but they are now able to speak for themselves and they have stated they feel able to say they want to remain with me.
So I am able to protect them better by separating from my wife.
My question is: given that she will threaten suicide and emotionally manipulate the children - given, also, that I do not wish her harm, only safety for everyone - should I let her friends, or any common friends, know my intentions? Until now, I haven't, believing that she should be almost the first to know; but letting others know, would both help her find support, and may help minimise manipulation?
