You are being stalked. Research the protections that stalkers need in your country - you might want to set up a website describing what's happening so you can point people to it. Include links to stalking information to avoid as many "it must be something you did" accusations as possible, although there will be some of those.

CLEARLY DOCUMENT EVERYTHING. At some point in the future you may want to go to the police and having everything they need neatly laid out is helpful to them.
