2. Don't Be a Flirt
If you are into a guy and he doesn't like you back, the worst thing you can do is flirt with him. All you are doing is making yourself more available to him, when your solution is to always become harder to get. Keep the body language to a minimum. That includes arm touching, turning anything he says into something sexual, and purposely trying to be around him. Rule on how to react when he doesn't like you, keep hands and feet away from boys at all times! There is a way to communicate with him in a monotone way just by staying neutral. You'll have no problem just by thinking of him as the creeper who is hitting on you when you go out.
