She sounds very self-centered, creepy, and sick in the head. For some reason, I would say she’s fixated on you, and it feels like a 5-year-old playground bully but worse as she’s a grown woman.

And most people don’t go out of their way to befriend children and follow children < 13 they don’t know on social media, so are you sure you even want validation from her?

Life isn’t fair, but hopefully one day, she’ll either change or pay for how she’s treated people. People who defend her or don’t care that their “friend” (you) is being harmed by this lady they’re obsessed with are kind of dicks, too.
