You're getting some great advice, and I hope you see that your W is not throwing some new twist on things that many of us haven't seen before. On the one hand, don't worry about it too much. She has no more idea than you do if she will fall in love with you again, that is only answered by the process (she of course can do so, but what you do and what she chooses are the determinants).
Also, despite what she says, this isn't baseball. You don't get three strikes and your out in Ms. And she doesn't get one chance of this. She is hurting and afraid that her heart will be broken and she'll never know love again. See that as what it is.
Now that said, don't just dismiss what she says as absurd or spewing or ranting. There are often nuggets of truth even when they re-write your history or say things that don't make sense. There are also often clues for what they are really wanting to see from you. They often are not the obvious (become super H).
Keep up with the validating, GAL, detachment, and keep things as light and friendly as you can. Good luck & sorry you are here.
