She is rude, aggressive, and extremely cruel to me. I've tried to keep her happy for years and years now. She relentlessly mocks me, taunts me, laughs at me, belittles me. She gets all raging and screams at me. DH and I put so much effort into helping her out, but she's just so incredibly vicious to us.
Most recent involved her absolutely losing her shit, slapping me, screaming at me, stomping off in a giant tantrum.
Oh and she screamed at me that I'm an evil cunt, she hates me. Then about an hour later apologised and asked if I'd bring her grocery shopping tomorrow. Then screamed and threw things at me again, slammed so many doors. This isn't normal, is it? And its okay to walk away?
