I'm in a ridiculaous situation !!?

You ever see that movie with Clint Eastwood "Play Misty For Me"? Man you are in it. She is obviously emotionally and mentally unbalanced. Her "looking out for you" sounds like she is stalking you. Her calling the cops is going to backfire on her. She's wasting their time and they won't put up with for that indefinitely. If she calls them again explain the situation to them (they probably already know). Find out what your options are. In the meantime delete all her text and phone addresses you have. And stay strictly away from her when ever possible.
