Thank you for the advice everyone, it is appreciated.

I've blocked her number so this will reduce any temptation on my part to contact her. I really don't talk to her either way to be honest, even by email.

She announced she was moving my kids to another state last year with OM without asking me or the court for consent to do this. She'll stop by and pick my kids up without telling me when I have them during the week.

This is what I am dealing with, so you can imagine my unhappiness with her for disrespecting every agreement we have.
