DS 13 and games with DD

[Mysecretgarden]

I am fed up with DS's behaviour with his sister 9.
As soon as she arrives from school he starts with :"I am going to beat you up."
Last weekend he tried to choke her for fun. Not sure how bad it was as I wasn't in the room and DD tend to over exaggerate so I am not really sure what happened. When I challenged him he said 'It was ok' as he 'only did it with one hand'.
DD can't watch a DVD in peace. He pretends to want to watch it too and then starts rough playing which invariably ends in tears. I really had enough of his rough playing which I find a bit sadistic.
he likes to pretend he is doing it as he finds it fun to make me react.
They are not with me very often so it is hard to monitor and have a followed up action plan.
AIBU, I told him his phone would be taken off if he did the choking thing again.

There will be support, although it's not strictly DV that's only because both are under 16.
I would call NSPCC.
From what you have said about your ex I would also get in touch with womens aid if you haven't already.
I'd also Google sibling abuse, the Wikipedia page is actually quite interesting especially the signs, risks etc part.
You really really need to do this OP, for all your sakes.

You could always take him down the police station and have an officer explain what 'assault' is and its ramifications.

He needs a sharp shock to stop that behaviour right now, and followed up with some help for him.

DontMindMe1 Yes I like the sound of this

Oh dear. What happens when brother starts to get a bit more interested in girls? Is he going to try it on with his sister? The very fact that he treats his sister to intimidation and rough play would be raising a very red flag.

You need to decide if your husband causing problems or the safety of your daughter is more important. That said,I think it must be gut wrenching to have a son act like this. You have my sympathy.

Have you told him he is a bully? Id start stopping his activities, taking his phone, removing access to wifi.
