my aunt and uncle are splitting up and pulling my cousin to pieces...

[ELF1981]

I'm so sad about it.
Basic version is that my aunt has been having an affair which was discovered about a month ago. They were trying to work it out etc but she was still with this bloke etc.
My 10 y/o cousin did not know what was going off, til she overheard this big fight with my aunt and uncle and they told her they were splitting up. She threw a big tantrum, cried her heart out etc. I took her out that day, she sobbed for hours. When they picked her up, they had decided to give it another go.
A week later, my cousin rang my dad, sobbing, asking for him to pick her up and take her to his house. Dad went to the house and they were screaming at each other, swearing, throwing stuff etc. Dad took her to his the following morning (because he wrongly worried what the implications would have been if he'd just taken her away from my aunts house in the middle of the night).
So anyway, they have decided to split up. They've been together for thirty years (since they were 13).
My cousin is in bits. I'm angry with my aunt because of things that happened (not just the affair / lies etc, but because she refused to see sense, even when this guy threatened to hurt my cousin, and turned up outside her school, my aunt did not have any warning bells go off). I'm feeling sorry for my uncle (he's not my blood relative but they have been together since before I was born) BUT I really feel for my cousin. How can I / what can I do to help her?
Sorry this is so long.

What a sad story. Great that you care so much about your cousin though. My parents split when I was 10yo and I imagine that she needs you to be consistent at the moment - normal things going on allow a child a bit of time to 'hide' in everyday life while they get their heads around what is happening, BUT she will also need time to talk and quite probably ask questions. She will be wondering about her future so if your aunt and uncle can get some basics straight for her that will help - where she will live & who will be her primary carer are crucial for her right now. Try to take your cues from her.
Should you be contacting the police about the boyfriend's threats towards your cousin and going to her school? DO NOT think it is not your place to do so as you are not her parent - if you have any concerns about this guy then call the police straight away - they can check his background amongst other things. Child protection is the job of every responsible and caring adult - better safe than sorry in my book. I hope you make some progress with this.

The police were involved re him turning up at the school, he was "given a warning" so I was told by my parents.
My aunt does not see sense, when he turned up outside the school she told my mum that he just wanted to see her. He also has a child, a fact he had hidden from my aunt.
I will see how my cousin goes. I've only got a two bed house and no spare bed, but might invest in a blow up bed thingy so she can sleep over and get away from things.

Glad to hear the police have been alerted and good for you for standing by your little cousin - she will really need an adult who is only interested in her and not themselves. Hope you find a nice blow up bed in the sales - kids are happy to sleep on just about anything, so even a spare duvet might do! Best wishes and hope it calms down soon.
