I told him today in one simple email, the following. I will just cut and paste this from now on. He emailed today wanting to discuss "altering" the sobriety clause of the parenting plan. My reply.
"I will continue to adhere strictly to the parenting plan as signed over the last two years, three different times, by two judges. Do not contact me anymore asking me to make changes to a finalized court order. Any additional communication you wish to engage in with me about court matters will need to come from your attorney. I will communicate directly with him, not with you, as he is your counsel. Thank you. Have a good rest of your week."
