Junior high is tough, and the social pressure is even rougher.
Can you drive? Do you have a car? Your own place?
Your relationship is going to be limited, and constrained to the bounds by which you are in. Just ask her if she wants to be your girlfriend, and pass notes, sit together at lunch, and talk on the phone at night. Dance at the school dances, and buy her a Christmas present.
I am sure she cannot date until she is 16, but would that preclude her from inviting you to her house for dinner? Or doing things with her family. Trust me, if dad likes you, he will be more then happy to drive you to love birds to a movie, and pick you up when it is over.
