I know its hard but Amy nailed it. He is pushing you. You back down now you will damn yourself forever because he will know he's got ya.
Let them call, let them email all they want. Turn off the phone, delete their emails, delete the VM. File an RO against her if you can and him too. Wait for the contempt hearing. Stop future tripping on the job. You have informed them of the circumstance. Trust he is not the first nutter they have dealt with.
You can't manage this dude. You play nice, he messes with you. You play fair, he messes with you. You file contempt, he messes with you. One time he is going to mess with you once too much. Even sociopaths know when to stop, when they get in real trouble.
Stay the course friend. You can do it.
