The note is actually a good thing. Now you know for sure that she has no interest in you right now. And why should she? Are you even friends with this girl? Do you talk with her on a regular basis? If not then she has no interest in you cause she doesn't even know you and you don't know her. If you like someone then talk to them and get to know them. Don't try to turn it into anything more than friends. Leave dating for High School. At your age your just looking to have a girlfriend as a status symbol not to find a partner for life. Ultimately that's what it's all about. Become good friends, take the next step into dating, and then move up to marriage. But give the friendship thing a few years before moving into the next stage.
