My boyfriend says that he doesn't like my type?

Umm, well first of all, you are 12. You shouldn't be having sex, and I know that you've probably heard this tons of times, but you're too young to be even thinking about relationships. They usually don't last at that age, and though they can be really fun, preserve yourself. As for the cutting, if you're depressed, you should see someone. You've probably heard that a million times too. As for the boy? He's a stereotypical bum, if you don't mind me saying so. He should judge based on personality, not stereotypes and looks and stuff. I'm 14 btw, if that helps.
