Yes, I agree it's premature to call them now. But if you did, it's not like they would arrest her or file charges. They would just talk to her and warn her to leave you alone. And you could get some documentation, w/o her even knowing that they wrote up the incident.I really don't want to file a police report, yet. It's not like she's done anything to me. Someone visiting her questioning her mental state could actually escalate the situation. IDK. I've never had to deal with something/someone like this before.
My husband is a police officer and I am telling you it is not too early to get a report done. It is for your safety. Document it now before something worse happens.
