I go back to TH's response. Is your NEW partner OK with you being friends with your Ex-Wife?
Maybe so, but in most cases, I'm betting not. That doesn't mean you can't be cordial or even friendly when it comes to your kids, but you probably cannot be friends.
I get this, but as a practical matter you presumably are going to be establishing some sort of relationship with your STBXS long before you have a new partner who is going to have any say in what you do.
