Honestly, the only thing you can do is step away, stop interacting with him except in case of extreme emergency regarding your child, and pretend he doesn't exist.
Was said on 1DEC....before the coparenting session where the C called him out on how immature his actions are and you jointly decided to co-parent.
Now that you have had that discussion, you have to follow through with it and that requires communication. That is DIM communication, not R type communication. Clear as mud right?
You will have to decide when it's important to involve your H and when it is something you can just handle on your own without any input from him.
Example - You contacted him about S14's FB page. You definitely should have. His response to it was completely inappropriate for the severity of the problem though and I think you need to bring that up for further discussion with C. That was appropriate contact though.
now.....
Don't contact him regarding the daily discipline issues. Here's an example for you from my own experience.
My son was with his dad when xh was living with ow for a weekend. She had a son who was 6 years younger than ours so it was never a good situation between the kids anyway. They had both kids at the same time one weekend and Marc got tired of her son's constant whining and pestering so he shoved him. The kid fell backward and smacked his head up against a dresser. No broken skin, just lots of crying and more whining and a small knot on his head. No, not an appropriate reaction by my son but with his Aspberger's he doesn't react well to others in his space in general let alone some young snot up in his face all the time. His dad decided to call me and proceed to tell me all about the incident, tell me I needed to come and 'pick up your son' because he can't be around her son. My response to that? I told him he could handle small discipline issues when OUR son was with him just like I did when he was with me and if he couldn't handle that then he didn't need any visitation at all. He put our son in the middle of this situation and he had to learn to settle their differences because this would be happening for years to come.
You see, this was only one small incident, nothing that could lead to a long term issue as long as it was nipped in the bud. He tried to put it all back on me because he wanted to appease his gf and give in to her and her whiny kid.
It's a balancing act but take your time with it. You have plenty of it!
