There's nothing you can do. Just let it go because you can't shake her out of her fog.
If she doesn't want to go to the game tonight, that's her choice. A poor one because you're having the children suffer by her not being there for support, but it's still her choice. She's going to have to live with the consequences now or in the future.
Your W chooses to stay away and has not gone into C at all. She chooses to hold on to the hurt she "believes" she has.
Unfortunately you can't do anything about it. Do what you can for yourself first and protect your kids from her hurricane of emotions.
M-43 W-40 2D - 9 and 5
Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
