Im worried about my sons girlfriend (16) Her father is excessively controlling. She is rarely allowed out of the house to see friends and when she is he dictates the terms eg can go to the local park only/must sit in their back garden. My son was out with the family one day and put his arm around her shoulders for a photo for the mum. Dad actually growled at him to stop it. When out with my son he wouldn't allow the pair of them to walk together, he pulled her away and physically held onto her so she had to walk with him. She has spent the summer holidays so far at his beck and call, all day every day, cooking/cleaning/going out with him. She has learnt just to get on with it and do what he says since the moods and anger if he is challenged are too much. However, even complying isn’t good enough. He tells her to cook him a meal, but then half way thro berates her for being busy cooking and accuses her of doing it to avoid going to the gym with him. He is basically emotionally manipulative as well as controlling. She has bouts of panic attacks/vomiting that I am convinced are down to the stress of the suffocating, micro managed nature of her life. He is a very sensitive and easily offended man so if I brought this up with him I fear we would be cut out of her life. What, if anything, can I do to help her?
