My grandsons wife (16 years old) will not allow him to be by himself. This even goes as far as going to the toilet, bathing, even leaving the room. She is very violent, she has cut him on the face badly. She is now pregnant, and I fear for the baby and my grandson, he has gone from a healthy 13stones down to about 6 stones with worry. He is totally terrified of her, and he is scared to do anything about it for fear of reprisals to him and the rest of the family. Please can you advise.
