Hello and welcome to Psych Central. I have to admit you have been through a lot with your EX and children. Your children sound effected by their environment and I feel that you should call someone in children services and keep a journal on what the children do when they are at your home for visitation. I feel that telling no one is dangerous not only for your children living with your Ex but your children living with you at this time. Can yor children receive counseling when they come to see you for visitation. Perhaps going to family counseling would help the children since you have a divided family at this time. I hope things turn out better for your family soon. Talking to a therapist can help at times when there is no other avenue to take to help you get the help you need with childrens services at this time. Take care of yourself. Soidhonia
