She has said that If I stop the court case then she will speak to the kids who may then wish to see me and that we go back to what the arrangements were before.
Do not stop the court application. She is emotionally blackmailing you and using your kids to control your actions.
It's very likely they have no idea what she is planning in her head so don't let her get inside yours!
You need that order in place to stop this and assert your rights which will limit her ability to control you. She doesn't have any "power" over your children. This is all based on what is right for kids and they have the right to spend time with both of their parents.
Sit tight. Talk to us. We all have to play the waiting game and this is one of the hardest parts of this process. Don't let the time consume you with worry and anxiety caused by overthinking or catastrophising (when someone assumes that the worst will happen). That can cause all sorts of additional problems for you, as I well know.
Invest that emotional currency in getting smart with the system. Get better at understanding it than her. Don't let yourself "suffer."
Put it all down from time to time and go and do something you enjoy. Try to fill this waiting period with healthy enjoyment not the trauma of the separation. It's not easy I know but you have to keep reminding yourself that time is always moving forward. The time will go slower if all you do is watch it. Your court date will come around soon enough.
