RTL, The reason why your W is trying to hurt you is because of a defense mechanism. She si trying to hurt you because of her own issues. Again, it is the same thing I am going through. It is the only thing she knows.
Try this one on for size... Saturday I get a text message asking what my plans were. I did not have any since our S was really sick and we agreed to making sure he had someone to stay with him throughout the weekend, the custody order went through Wednesday and we are supposed to trade off every weekend. My STBX asked if I could watch Jack, which I did not have a problem with. She then goes out with the guy she has been dating since October and he comes to the house to pick her up. Initally there was a little shock to it but what does that say about the guy she has invested so much time with??? Ultimately, she is going to try and get a rise out of you anyway possible. She will continue to do so for some time. You need to focus on you and your D. I know it is tough but there will be growth and a shift in priorities to which she will not have the same effect as she does now.
Keep working through this. Post on your boards, talk to you trust, and make sure you are taking care of you. Once the decree from the courts comes down, she is on her own. If she does not want to work with it, she is just hurting her future with your D. You can not control it but the courts will give you the stability you desire.
