I need some advice to help my brother. He's going through divorce, and has 3 daughters 13, 4 & 2 years old. The children are currently living with the mother, therefore, she is manipulating the children against the father, specially the 13th years old. The few times he has seen her, she asked him about problems that she should not even be aware of, or at least not concern about; she is very involved in all the divorce issues. Every time my brother sees his daughter, he explains her that she should not worry about it, those are problems between the mother and him, she should not be worrying about it, they're working to find a solution, so she changes her attitude, and acts normally, then she goes back to the mother and when come back to see the father everything comes back, and she shows a very bad attitude. I see my brother suffering for this situation with his children, and I don't know what to advice him, he loves his children very much, and this is a very sad situation. Please advice. Thank you
