I think Tim is spot on......I would also like to add that if he arrives at your door....it doesn't matter what time of day or night, do not answer the door but call the police and say you have an unwanted person at your door and you are in fear. They will come and remove him from your property. Also, if you haven't done so, keep a diary of the times he has contacted you and the outcome of those contacts to present to the police/court if need be. Having something concrete for them to see helps in determining if indeed he is stalking you and if indeed you should receive a restraining order.
I wish you well!
