I wouldn't respond. You do realize that you can't rationalize w/someone who isn't rational at the moment? It's like having a discussion w/an orange. She's emotional and quite frankly, her reality is her reality, just as you reality is yours. Please stop trying to rush the process. As long as you know that what she's saying is Memorex, then let it go for now.
The more you point out things to her, the more justification you are giving her for separating from you.
Keep the focus on you and allow her to play out all of the Memorex tapes she wants for now.
If you do respond to her, just say "I'm sorry you thought I wasn't treating you well" and leave it alone. Otherwise, just leave it alone. Don't touch the hot stove again.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
