Jon,
Did you notice the first word in the title of your post? It is PAST TENSE!
You know your own preferrences...your intentions.
Get yourself good counselling to help with the change you already know you will make.
Take the daughter/children with you, or send them on their own way with your kindly support when they are ready.
You don't have to live any way you don't want to...period! ...No matter what the woman says.
The need to be 'right' is a figment of her imagination. Leave her to it, for you can't change her, as much as you may wish to.
You are the one carrying the scars to prove it.
Get the children out, too. And get counselling and legal help...they will know the appropriate options.
We begin to suspect another's words are true, that we are useless. You are going to feel like a brand new person the moment you take action.
Form your own life, now.
Getting counselling for yourself is a great first step! Getting separate counselling for the children is an even finer second step.
This may be the finest thing you do in your life...save yourself and save the children.
My best,
Fledgling
