My ex broke up with me about a year ago. We are still friends on social media and have a bunch of mutuals. She would never write anything bad about me on social but recently one of our mutual friends showed me this Facebook group where she is basically talking shit on me daily. It's like every little thing. Like I said its been a year and she will comment or bash me almost weekly. Im just wondering why someone would do this and she doesn't really say anything to me about it.
