When my XH did similar things to me with the court system I felt overwhelmed like you do. Is there any way you can find a child or family therapist that will testify for the children? There are two in my area. It helps for the kids to be able to talk to someone that is trained in helping children and for seeing through the BS their dad is doing. The therapist here are also experienced in court cases and have a good report with the judges. If you could find someone there that does this it might be a help. Surely a judge will see this man does not care about these children and does not have their best interest in mind. What kind of parent would not have contact with their children for four months because of a "misunderstanding" in the courts?
