The issue with court and CAFCASS, things are very uncertain. Things are up in the air and when you go into that area, you do not know what can happen if you understand. One thing I will say is please get a good representation as they will fight your back.
I will also say please keep doing what you are doing for your kids as I am in the same situation and my Ex is stating that I am an unfit mother and how I am coaching my daughter. They say loads of these things and I know they are not true but how the court system likes these sorts of things.
