I think it would depend if she is still in her fog or not. Situations that would upset a normal person have seemingly no effect on ex. He is so wrapped up in his fog that he can't see his hand in front of him.
I hope she feels it and knows that she is letting her kids down because that might be the thing to get her to change her behavior.
