Yeah, that's the best advice. Document everything she does that bothers you. Make sure you use date and time notations for each event. If it ever goes to a court hearing, you'll need that timeline of events to back up what you say. Always note and document witnesses, if any, to any negative event. Even reluctant witnesses can be subpoenaed and put under oath.
