As very very old ghost here. I would say that your guys still young and still a lot to learn ahead of you. But, if you really love her, you first have to make her smile, laugh, be respectful, etc. I bet you already know that and doing that as well. If she wants to hug you, never say "No"...hug her back...it is just a hug!. One thing that every guy should know is that if you like a girl, tell her straight forward that you like her...if she smiles that means she shares same interests. Since you are still kids not even in the Teens yet, you must make sure to think proactively and let your hearts guide you if a relationship is developed and don't let the conscience fool you because otherwise you will be facing lot's of trouble ahead.
Like my father used to say "If you like a girl, tell her that you like her before someone else beat you ahead and win her parents." On Valentines day give her just a single red rose and say this while you give her the rose "This rose is as pretty as you and hope that our relationship grows even more further than it is now" just watch her reaction...that will tell you a lot.
