ignore her completely. laugh at her when you see her. she'll probably get upset that you aren't giving her any more attention. know what? let's pretend she crawls back to you and begs you to take her... wow... lucky you, huh? wow, this is a great idea! you owe me 100 dollars.
Explain that you aren't stalking her and that you just really like her.
take a picture of his bedroom window, email it to him with a text: i will come back when you ask me to!
you are stalking her..hmmmmm..stop that..now :))
Stop doing whatever it is you're doing.
Stop stalking her.
You're making her feel uncomfortable obviously.
You might not think its stalking, but she obviously does.
if she thinks ur stalkin, ya should lay off fer a while till she comes around
