How do you know if you haven't done it? All this stuff you've posted is what you "think".
"she said she pretty much made up her mind before i told her not to bother coming home"

How about getting up and doing something? You wanted advice and you got it. Give it a shot. She's already gone so what have you got to lose? At least you know for sure. She has to feel like the door is still open and that you're not going to kick her out again the next time you get upset.

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