How do I get an older girl to like me?

im 14, in 8th grade, and I like this girl who's 16 and a junior. we have a study hall together so we have an hour alone every day. we talk a lot. we both play basketball and think alike. we exchange hugs and she loves the way I smell. we both think each other is pretty/cute. we both say we don't like anyone. but we say it while smiling and I know I like jer and I think she mightike me. at my sis' party a few days ago we played sardines. we hid together for half an hour. then we talked alone. she was with me over all of her friends. I think she likes me. were the same height. the only thing is she gives out alot of hugs. she's really shy and some days doesnt talk to me much. so sometimes she acts like she likes me. sometimes not. anyway I can get her to like me? tips? thanks
