My Dd is saying her dad physically and sexually abused her a few days ago. She lives with him. She's now here with me and the police have said for her not to have any contact with him until they have seen her later today and investigated. She's 16. Today despite police advice she has been in contact with him because she wanted him to do something for her. We have a tricky relationship and I'm doing my best to protect her and am frustrated that she is in contact with him against police advice. How can I handle this?
