Unfortunately none of these suggestions are practical. JC this sounds pretty bad. To me, it may be a good idea to spend some time away from your place or perhaps even ask a friend to stay with you for awhile until you get squared away in your new place. Good that you have a dog but in this case it sounds like a large mean dog may be needed.

Or perhaps you can ask JP to come over with her gun and that should keep this stalker at bay for awhile.

Seriously though at this point it may be best to stay away for awhile.

On a side note I did take a handgun class and loved it and I would strongly advocate that. However if you decide to purchase one there is a bit of a waiting period. It is not a bad idea though.
