You can request copies of your file. that way you can see in the files what if anything she has that you may have said to her. If she wont give you the files then you can go to domestic violence. tell them the situation with your husband, conversations with domestic violence are confidential between you and DV unless there is court action. Tell them about being in therapy with this nut case in the past. you are thinking about reporting her but she's black mailing you from doing it by saying there something in the files. Sign a release form with DV to the DV therapist can then get your files from the nut case black mailer. then the DV therapist can tell you whats in the file and help you get out of the black mailing situation and help you report her to the state ethics board.
