Lidia’s answer: You can hardly prevent people from lying. However, when you say “domestic violence” you need to be clearer on what you mean. If you mean criminal charges, there must be some evidence for the Commonwealth to file charges. If you mean PFA, since you already have no contact with her, a PFA should not hurt you. Please make sure you are really staying away from her. Don’t talk to her either. That would limit her ability to threaten you
