So, yesterday we celebrated our mum, she and dad live with me, single brother is in our bubble. Brother has a drink problem I believe. Was all fine, eating nice food, brother is I notice tipping gin down his neck rather fast. No issue he's 43 can do what he likes. He's also a massive piss taker, if he can take the piss out of anything he will. My husband is telling dad the shelves in the shed need fixing, brother cracks a joke about being wonky. I reply with Yh bit like you, again joking. He picks his plate up and flings it at me. Calls me a fucking cunt and walks out. I've told mum I don't want him here for a bit, he needs to grow up, stop drinking and say sorry. She's adamant that he doesn't remember so it's ok. Aibu to stick to my guns x
