Try reading the 37 rules tomorrow morning. Find a quick way to detach. I know mild anger has this short-term effect on me, giving me a clearer head for a few hours. Might be enough to go through this ordeal without pleading, giving up, etc.
Remember: nothing you will say tomorrow will make her stay. Except perhaps "Fine, go. I'll be ok."
Courage. And report back.
