So tonight I got a not so polite message off my brothers gf asking why I slagged her son of which I didn’t I simply said that her son is not my mums grandchild and she bothers with him more then my children. Which I got abuse called a cunt every swear word under the sun. I’ve only ever talked to my mum about her so it obviously was my mum causing trouble. Then I messaged my mum saying why did you tell her about our private stuff between me and you she lied and said she never.So I messaged my mum again and was like look stop lying have you been bitching then she just laughs and it’s like your being childish I won’t trust you again. Anyone got any advice my mum just seems toxic 😢
