Okay, I promise you, he isn't the first guy that's liked you, and I'm sure that he won't be your last, either. Try dating him if you'd like. Maybe you will start liking him again. And if you don't, you have the rest of your life to get a guy that I'm sure will love you for who you are :P
Please, do not scratch. This is coming from personal experience. You keep wanting to do it more and more, and then it gets deeper and deeper, till you're eventually cutting, and it does leave scars. My arm is all up because of it. I promise you, the pain isn't worth it. It may seem like it, but it isn't. I care. I don't want you hurt. Please...
FIGHT FOR EQUALITY!
