I thought about your situation over the weekend, and wanted to touch on something that you may not realize. You have mentioned that you are frustrated, because your W has lied to you, and is not consistent with a parenting schedule. I am sure there are other things that are frustrating to you.
Here's the thing. You are contributing to your situation and your frustration. Why? The simple fact that you are enabling her.
You are choosing to remain dark/idle while she wonders around aimlessly, in hopes that your interactions with her improve. It is like dealing with a petulant child. They will push and push to see how are they can push. Your W knows that you are there, and she knows how far she can push. There isn't a motivation for her to change. Your W is using the D word to keep you in a place of fear, and it is working.
The point of my post, is for you to look within to identify how you are contributing to your frustration by enabling her. You have a bigger part of this than you realize. If/When you change, the dynamics of your sitch will inevitably follow.
Hope this helps.
