I'm stoked that you had a great couple of days. It is also great to hear that your W may be coming around a bit.
She dressed up for you, eh? Nice! It also seems as if the line from the lawyer about squeezing you was left in on purpose. She may not have consciously left it in, but she most likely wanted you to see it.
Her showing remorse and sadness is a good sign. I also like your plan to respond, but be sure you aren't too confrontational or you know she'll be livid.
Keep going and I'm looking forward to hearing how your response to her boo-hoo e-mail was received.
