You’re making passive-aggressive posts
You’re also posting passive-aggressive rants on social media that are clearly about this person. You’re sharing long “hypothetical” scenarios that very much resemble what happened with you and your friend. You’re again exaggerating her mistakes. Then you’re throwing it to the Facebook community, asking them what they think, or who they think is wrong in the situation. You’ve worded the story in such a way that people will obviously take your side. Again, you haven’t blocked the friend you’re mad at because you want her to see these posts. And you know if she tries to defend herself in your comments, she’ll get attacked.
