As a rational adult (female, disclaimer), FIRST thought:
“Why wasn’t mom charged? She KNEW he had a habit of doing this and in some degree was an enabler of this behavior.”
ONLY rational reason would be: She’s a female.
She really OUGHT to be charged.
What was she supposed to do, quit her job? She seems to have been the breadwinner. No, she wasn't even there. This is his fault. She can't be responsible for the money AND overseeing her husband as if he were one of the children.
