There is a woman (friend of her family) who is slandering my name and threatening my fiancee by text message and phone even though there is no physical harm done yet is there a way to get a protective order or restraining order against this woman?

She has become a real nuisance as in slandering my name planning for a wedding she has gone to places of business telling them not to do business with me because she has accused me of hitting my fiancee which I have never done she has called the police on me and cops find no evidence of me hitting my fiancee she has also claimed that I have done damage to their house and vehicles which again I have never done and they have no proof.

Any advice will be greatly appreciated I know its not real legal advice but just anything leading me to a right direction I haven't gotten with my attorney yet but threats came in over the weekend and just want to make sure I have ground before going to see an attorney and paying the fees for something I can maybe do without an attorney.
Thank you all so much.
