She just sent another email that says " Just note, I was out of town for 2 days, and had hardly spoken to you at all when whatever triggered you happened. Please note, I also said over a week ago I would not be staying there when you're there. I'm sorry if the empty house is a "stressful environment".

She did say this but she was only away for 2 days, then she stayed at the house and then she was out of town for 2 nights. Then she stayed again. This is a great example of how she lives completely outside of reality.

not sure how to respond or if I even should?
