Well, the police officer talked with my ex-mother in law. Apparently she started screaming at him about what a bad, evil person I am, etc. and he very calmly explained to her that if she felt she had been treated unjustly, she needed to follow proper channels, like the court system. At this point she started mumbling and backed down. He explained that she cannot call me again or they will issue a warrant for her arrest.
The officer called me to give me an overview, he was very nice, but it kind of cracked me up when he said, "If she shows up at your door, don't even open it, just call us."
It's nice to not feel ill everytime the phone rings.....
