First off I am really sorry about your situation. I have been following you for the last year because there are some similarities in our sitches. I was really hoping it would work out for you.
My wife has yet to pull the trigger on a separation/divorce mainly I believe because of guilt/kids/finances/family/friends. She is a 2 Enneagram "The Helper".
I am struggling with accepting that even if my wife stays it is more for those reasons then actually wanting to be with me.
