Sorry for any typos
Here goes
My sister is 27 and has been a single parent since the age of 15. She's worked hard and done everything herself until now. She's met someone a few months ago from Romania and he's extremely violent. There's no doors or gates left on her house and he's violent towards her. He goes and a few hours later he's back even though police and social services are involved. I don't get why she's taking him back because she's never ever taken any shit (mainly the reason she's been single for 12 years). He's extremely racist towards my sisters partner and her daughter who are African 
and he tells them all the time he hates black people so my sister doesn't visit anymore even though she lives about 20 houses away 
he said he's got a gun and knives that his friend is saving for him and he was a hit man back in Romania 
this alone would've have made me run a mile. We don't know where he lives only his place of work and we can now no longer visit as he growls at us and makes very uncomfortable so my sister asks us to leave 😖 how the hell can we help her and my niece if she's not willing to do anything and then accepts him back when the police have gone oops forgot to add she's also pregnant to him 😳😳 around 8 weeks ffs more I write the worse it sounds.
