Legally, your best course of action is to
1. Post a no-trespassing sign on your property, that way if he comes onto the property uninvited you have a legal option.
2. If you are really afraid of him (and it sounds like you have good reason to be since he's showing some stalker signs here), file a request for a restraining order- if not NOW, then at least after he comes there to bother you.

That way, if he does come near you, it's a crime. When you file the protection order, he will be served papers telling him all that he needs to know, so he shouldn't have to call you or anything like that. TN has some decent laws against stalking now, and it's something the police departments (at least around k-town) have started to take very seriously.

Hugs and best of luck!
