One year later and she hasnt stopped bullying

Doesnt matter if I block her. She private messages me telling me to go back with my ex because he harassed her. When I left, she ended up with him and getting pregnant. She puts hate all over her fb page about me and my new relationship. She gets into my personal business all the time. My new relationship called her out on it and was trying to get her to stop and move on. This has been going on for a year. I accepted her help a long time ago and now I am being backstabbed. The picture attached is the most recent, but this is a daily thing. She needs to be taught a lesson.
