So I had a brief discussion with the ex-a about what we will discuss in the mediation session. My main concern is having my son exposed to people who are displaying high risk behavior. He tried all the usual manipulations, denial, minimizing, making himself a victim, exposing my mistakes, phoning to control the conversation. The great part about it. I had zero emotional reaction to any of it. I just simply asked for what I wanted. I did not answer the phone call. Normally, if I answer he would scream until he could scare me into silence. I just continued the conversation through email. It was empowering. The reason for the discussion was that he had my son and was asking for another overnight visit. I originally agreed until he gave me more information and then I said I have changed my mind.
