Hello mvg. Sorry to hear about your W. Hope you get free soon.
No legal parenting plan for us. We just started this 2.5 weeks ago. My W keeps threatening a mediator when she feels she's losing control. Just be agreeable and clear in your communications. I agree to let her see S11 as much as she wants though I keep him more nights so far. Despite our screaming, she is respectful in most communications. It took a while of firm boundaries to get there. I only respond to my Ws texts or VM. I usually don't answer her calls. When I do I get in trouble with anger.
Good luck.
