I just got a message saying how this isn’t fair and the kids should be on their house and that she can’t bring them back because of how stubborn I am being.
I am assuming you are not a threat. This statement is part of your evidence that she is the one trying to manipulate you and everyone else.
It is critical for you to keep good records of every interaction. Keep your records organized. I had a daytimer that I could write in with details.
One of your best tools is to agree with her:
W:"This isn't fair and the kids should be in their house. I can't bring them there because of how stubborn you are being." H:"You are right. I believe it is best if we exchange the children in public. The police station or McDonalds parking lot works for me. Let me know which location works for you. If neither of these work for you, give me a couple places that do work for you. Regards, H"
