My ex girlfriend is telling everyone that she's pregnant, and going so far as to post on Craigslist that an emergency hearing was done in her state for the rights of the unborn child, even though I received no correspondence saying there was one. She even denied my requests for proof of pregnancy and a paternity test. She lied about getting her birth control shot. She has put out on several internet forums very personal information that I've told her. What can I do to get her to stop?
