Just wanted to comment on one thing from your other thread. I think you did the right thing with notifying her when your daughter got hurt. There is no need to bring children into the war. A child deserves both parents there. I know as a mom I would be very upset if my ex husband wouldn't have notified me. My kid's are older now and he hardly seen them growing up per his selfishness. But still I would have been upset if he didn't tell me. In fact believe me I would have used it legally against him. That's how protective I am of my kiddo's.
So I think you did the right thing. : ) I also really liked the e-mail you wrote. I think she is trying to test you now. I would stick to your guns all the way. If you don't now then you will lose all credibility.
