So, I confronted her on the "Poisoning of the Well". It went like this:
Me: I'd like to talk with you about the kids. Her: Let me finish up what I'm doing.
A few moments later...
Me: We had agreed that we would split 50/50 the placement, custody etc. of the kids. Her: Yes we did.
Me: The kids have said that you told them that they would spend most of the time with you. They also said that you told them I don't like your family, that I'm mean to you, that I yell at you, etc. The courts call this "Interference". If you, your friends, your family, whomever continue this behavior, I will take this to the courts.
Then the Alien Speak...
Her: You know, I can twist what they say about you, around to, you know, blah, blah, blah, blah... I didn't think you would really get your own place, blah, blah, blah, blah...
