Is AUTHOR wrong in the post ? POST : So about a week ago I got into an argument with my girlfriends mom over some stuff she posted on facebook. Basically for no reason I can figure out she made a long post about how my mom was drinking and driving, encouraged me and my gf to have sex, etc. None of this was true. She never used names but she was descriptive enough to where a good amount of people would know who she was talking about. When I learned about this I messaged my girlfriend telling her I was upset and asking her why her mom would think all that, she said she didn't know but she'd ask her mom. A few minutes I got a message from her mom where she said everything she said was true and added in a little remark about how she felt sorry for me. I'll admit, I got angry so this might be where IATA, I sent her an angry message about how everything she said wasn't true, even using some certain 4 letter words I really shouldn't have. Anyways, after that she messaged my mom about how disrespectful I was for cussing around her (side note: she cussed a lot around me a lot) and how she doesn't want me to be around her daughter anymore. Anyways, now our relationship is over and I'm wondering AITA.
