Arika is your girlfriend I guess?
Let him see you guys doing as much as possible whenever possible.... you are most likely not part of his delusion....
so when he sees you guys not creeped out by him & instead rubbing it in his face that he can't have her & you can.... also save his letters and other junk for these periods and after you're done making out a little (on guard of course) --- but seemingly unphased by the guy.... throw his junk back at him at laugh. Call him a loser. Tell him he's pathetic. If he wants to hang around and stalk you guys, make it PAINFUL for him. But don't feed him with fear & show him he creeps you guys out.
He will be forced to show his hand.
Either he'll get sad and puss out and fade from the scene because it's no fun for him anymore....
Or hes a true madman and he'll try to actually harm you or her - and then he can spend some time in jail, or, depending on where you live... you can kill him in self defense.
WARNING: Use your own best judgement here. This could get you or her killed
