Been here did this, I think many of us have, it's a game. Don't play it. All the advice is great that you have been given. But you honestly need to sit down and write down everything that you want included in your order and then mark off what is important. After that, be done with it and ignore the game until it comes to a large issue.
Because here's the reality of this game that sometimes NCP's play, no matter what you do, what you say, what you add to that court order, they will continuously find a loop hole and attempt to irritate you. You can either drive yourself crazy and break the bank, or you can defeat the BS from the word go. So here's my opinion and advice and it worked for me, but unfortunately the outcome was him disappearing on my now S4 when he was 2.
Get on the site Our Family Wizard, use it, set up phone communication only in an emergency, when he has kiddos, check it once daily, when you have them, update as needed and check it no more then twice a week and DO NOT answer anything that isn't about kiddos. When you do answer practice writing it in less then 5 sentences. Do not set up the notifications to email you. WAIT 1-2 hours before answering.
You are allowed to designate a third party, use them, do not go, kiss kiddos goodbye at home, tell that third party to relay nothing, write down instructions for meds or the like on paper. Tell third party that you don't want to know what was said or done. If it endangers the kids, that person is at the PD, they go inside and report it, then notify you, otherwise, tell yourself you don't want or need to know. He wants your reaction, not theirs. If he speaks about you to them, don't react, they say nothing.
It will get worse before it gets better, be prepared for him to try and find that button, if you slip, forgive yourself and keep moving forward. It takes time. But I hope your outcome is different then mine. Mine showed me that our child was not his concern if he could not get me to engage and now I have a 4 year old in therapy because he didn't understand. Luckily I do have a friend(not romantic) who has stepped up and is being a "male figure" for him, along with his older brothers.
