If the complainant has not ceased his harassing conduct, you may wish to consider instituting a lawsuit seeking damages for abuse of process (which would apply to the domestic violence orders) and malicious prosecution (which would apply to the false criminal charges). As part of such a suit, you could also seek a permanent injunction. Of course to succeed with any of these claims, you would have to prove your allegations in court, which would probably require that you pay substantial sums for an attorney, since these are not easy causes of action.
Also, stalking is a serious criminal offense. If you are using that term literally--meaning that the obsessed fellow is following you, lurking around your home or place of business to spy on you, and engaging in similar conduct for the purpose of disturbing you--then you really should report his conduct to the police, speak to the State's Attorney for your county, or visit a District Court commissioner to file an Application for a Statement of Charges.
