Just before Christmas my partner and I both fell out with his sister.
She kicked off for no reason other then for the sake of it. She screamed at us chucked stuff about and hit my partner she even ragged her own 12 month old son about.
My partners 8 year old daughter was there and absolutely petrified of her auntie and never wants to see her again.
I think it may be partly because she did coke and weed but had to stop cold turkey because of being pregnant.
My partner and I have decided we want a baby but I don't want his sister around them unless I'm there to know they're safe.
I've explained I don't trust his sister because she's unstable has temper issues and didn't even care about possibly hurting her own baby.
He's saying I'm being controlling and unreasonable because when they make up he has every right to take his child there.
I just need a bit of advice as I don't know whether I'm wrong to not want his sister by my future baby without me
