Hmm, I dont want to be rude, but I want to be completly honest with you. I dont think she likes you back. Her being nice to you doesnt equal romantic interest. Ive had a guy tell me he liked me as more than a friend, I said I didnt feel the same, but I would love to remain friends if he was okay with it. To this day we remaind friends, and I dont know if he ever got over me, but we talk as friends and I try to help him out whenever he needs it. I see her as doing the same thing (Though I could be wrong!). She could treasure your friendship, and want to remain friends. Also, she told you she liked a boy. If she liked you, why would she lie about that?Stay positive! It doesnt mean you have to lose her forever! You can be good friends and still enjoy her company. As for you moving on, when your at home, to keep your thoughts away from her, try to busy yourself. Work out, draw, read, watch a movie, video games, or start hanging out with other friends to keep your mind off her. Eventually it goes away, thought it might take a bit. At least, thats how I dealt with a similar issue.Go out and try to meet someone new! :) Hope everything gets better for you!
