Hi. It's quite tricky to write every detail of this down - it would take forever, so I am going to try, as succinctly as possible to put into words something I need some advice on.
My mum, my younger sister, and her DS (my nephew) all live in my mums house. My Dsis has a different father to me, who is dead and was emotionally abusive towards us. Physically towards my mum. He died when Dsis was 6, I was 13.
My Dsis is abusive. She shouts at her son regularly, she manhandles him at times. I don't think she hits him. I know she has kicked him once.
Her behaviour towards my mother is awful. I have watched her grab her and shout at her. She gets in her face and they argue constantly. When she was a child she kicked her and DM ended up in hospital with an injured hand. She has no job, no money, is clearly depressed. I am angry with her, but worried about her too. She won't take antiD's. I get almost daily phonecalls from my mum despairing at her mistreatment/neglect of her son (my DM looks after my DN most of the time as my Dsis stays out all night a number of times per week).
Phonecall this morning was distressing. My Dsis had threatened to punch DM, in front of DN. He went to school scared and crying because of her shouting. He apparently regularly goes to school crying and asking my mum to please tell his dad/the teacher that his mummy shouts.
His dad is lovely. Could no longer put up with the turbulence of his relationship with Dsis and now has a new girlfriend and lives with her. He doesn't know how to protect his son.
Having been through emotional abuse as I child, I am very clear that this poor boy (who is 5) need protecting from his mother (not necessarily taken away, but safeguarding in some way). More than that though, I want my mum to stay safe. She is 61 and doesn't need violent threats. She says she won't kick my Dsis out until my DN is safe.
I guess I'm asking does anyone have any advice or experience of how this can be done. His dad says he is saving up the money to try for a custody battle I guess, but I have a feeling that the threats of violence will turn into actual violence very soon. I have told DM to call the police when she is threatened. She is scared my Dsis will leave with my DN and that he will be frightened.
There is loads more, but this is getting very long. Thanks for reading.
