my exgf and I being broken up in august of 2012, two years later she is still inappropriately contacting my friends and family to inquire about me.
Lack of support from the court? Some have found that their courts were reluctant to take action for what were lesser offenses. Sometimes you have to describe it properly so they don't see it as just irritation in your life. For example, be sure to use examples that demonstrate 'harassment' or 'stalking'. Listing the DV too would be appropriate and may tip the scales into action but but be aware it isn't considered urgent since it was a couple years ago. Those key words or similar ones may trigger a better response than just "she is bothering me, my family and my friends".
Have you considered first hiring a lawyer or solicitor to write her a clear letter advising her to cease and desist from intruding upon your life? That may be enough to get her to back off. Maybe.
Escalation or 'extinction burst' is possible, but I'm not sure, after two years, if she would make things that much worse, just hard to say either way.
