First off, forget about all your "facts". You're doing exactly what she wants you to. She claims she feels "guilty" etc., when in actuality she wants to blame you for all her bad decisions. Period.
So if you don't want to file, I would ignore her. Just flat out ignore her. Give her 'yes and no' answers. That's it. Act as if you're the happiest person on earth.
This will irritate her to no end. Oh she will continue to push your buttons. Gently remind her that you will not be spoken to in that manner and walk away. This will get her pissed off.
Meanwhile, go out with friends, for a walk, whatever. Show her that the universe does not revolve around her.
Forget about what she told you before. You start steering the ship for a change.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
