Go to the police now, then. It's that simple. Ugly, or dead?

If you have told him you will get a restraining order, and you feel threatened by his behavior already, and he still persists, you go to the police, and you tell them, "I want you to be aware. I know you can't do anything, but I need you to know about it." and be honest with them and up-front. Tell them you're worried about pictures you have posted that are a bit revealing (they don't need to know more than that). Tell them you are scared of the harassment. Tell them you think he is tracking your IP address. Then, tell your IP provider that you need a new IP address IMMEDIATELY because you are being harassed, see what they can do for you.

If nothing else, if he does contact you further, you should begin to save the PMs and emails.
