Name change here.
My dad has always been a difficlut, controlling man who has treated my mum as a general dogsbody, verbal punchbag and general whipping boy. He is an old man now and recently has become more and more aggressive to my mum. Over the last week she hasnt been able to leave the house, he keeps her awake all night throwing things at her door (separate rooms), swears and shouts non-stop all day, he has been throwing bins, folders and books at her today. 2 nights ago she spent the night fully dressed and standing by the front door with her keys in her hand because she was so scared.
He frequently goes off wandering and she has to go and retrieve him from neighbours/shops/ the police station. When they go in shops he is abusive to staff. He has now started wandering around with no clothes on (in the house but prob neighbours can see). She is so deeply ashamed and humiliated by his actions. She wont ask for help.
He controls all the finances, she has no money of her own.
I have begged her to leave him. She wont. I am concerned for her safety and her mental and physical well-being.
He is in his 80s, she is 75.
I dont know what to do.
