To phone the police on my brother?

[HotCrossPun]

Bit of background - I have a DB and DS who live with my parents. They are of similar age (late teens.)

My brother is over 6 foot, he is generally lovely, really polite, good fun and kind.

However, over the last 6 months my sister has alerted me to a number of incidents where he has hit her after an argument.

She phoned me in tears a few months ago because of it and then a few days ago she showed me a picture on her phone of her bruised legs after he had hit her again.

It would take an age to explain the dynamic of our family, but basically my parents don't have that 'care' gene that most parents do.

They are especially hard on my sister. If her and my brother have an argument and she tries to tell my mum or dad was has happened she is accused of being 'hysterical' and is often punished anyway.

When I saw the picture of her legs I was shocked and so angry, she must have about 20 different bruises all up her legs, all quite big.

IMO my parents are at fault. They take no part in raising my little brother and sister, they have to work out all conflicts themselves. As such, my brother is getting angry, lashing out, and then there is no consequences for his behaviour so he keeps on doing it.

WIBU to phone the non-emergency number the next time something like this happens? It would cause major ructions in the family, and my parents would no doubt place most of the blame on my sister and then punish her afterwards. But what is the alternative?

Brother and DP have a great relationship, but at the moment DP is a bit shocked (I showed him the photo) so I'll speak to him first and then see where to go from there.

Would it be worth a phone call to Women's Aid to ask their advice? They may be able to offer some insight.

You might also want to ask MNHQ to move this thread to relationships - you might get a better response if it isn't under the red flag of AIBU.

I would call a family meeting with parents, db and dsis.

I would be quite explicit that your parents are poor parents in your experience and that it is a disgrace they have allowed it to go this far. Then explain to your db that you will call the police if this continues and to your sis that she has your support and should not accept behaviour like that from anyone.

I realise that would be a tough meeting but so would dealing with the fallout from calling the police or having a word with db and his running to tell your parents.

This way you can ensure that your message comes over as you intend, there are no chinese whispers and you can assure all if them that this comes from a place of love of them and your hoping that it can be resolved amicably.

Ps maybe not so much focusing on the parenting come to think of it - but make sure they realise they have played a part and have to address it as parents.
