Ever won over a guy who was hung up on someone else?

Yes, unintentionally. The guy stalks me now, though. He was dating another girl and he would stare at me everyday. Then he stole my journal from the crate they were in inside the classroom and wrote a long story about how he broke up with the girl and how he did it for me but he still liked her blah blah blah. So at that point I took it to the schools counselor and she took care of it. But he still stares, and now its summer so I get a break. But I can't go to the police, were 12 or 13 and going to 8th grade.
