It seems that one very important fact, IMO, that was listed in the very first post of this thread is being overlooked or ignored. Father has SUPERVISED visitation. There has to be a reason why his visits have to be supervised.
As a child of divorced parents that was forced to spend time with a mother that clearly was more concerned with her own life and whatever male was in the picture at the time, I know that you can not force a "happy" relationship between parent and child. I also had to go to court to explain to the judge who I wanted to live with because my mother was fighting my dad for custody, even though she was absent completely for over a year after telling me that I was just staying with my dad "for the summer". If the kids don't want to spend time with their father, I feel that he has done something or said something to them to cause this. No matter what the mother may say to them at 15 the oldest knows what is true and what is not.
The father ruined any chance he may of had of reconnecting with his kids when he decided that the trip to Israel was more important than spending time with his kids. He left them in a juvie detention hall for spite, or so it seems. And if the judge really did at one time work with the father's lawyer, she should have never been a part of the case to begin with.
MOO
