Haters That Never Stop Hating

It's so annoying when people constantly have to put others down. Why do they get obsessed? I've got this woman, the ex-wife of my ex-boyfriend, who can't seem to let anything go. First off she told me, while she was still married, that she wanted me to date her husband. I told her no but later, once the divorce was final, I dated him. She seems to think we were together before then which doesn't make sense. We broke up rather soon after that and she knows that. She also knows we are no longer friends yet she still harasses me and my bestie because she says we caused her divorce. It's like she thinks that it doesn't matter that she cheated on him many times before they were divorced. She told us her husband was abusive. I don't get it. Why is she harassing me and my friend when he's the one she'd mad at. Especially when I'm not his friend or anything. It's annoying. I'm looking forward to the day when the police arrest her and she gets in trouble for everything she's done.
