I think i like my friend ?

ok its this one girl at high school were both in the 9th grade and i really like her.so before she liked i think 4 boys lol , but i kept teasing her about them and that what and who would would mainly talk about her and those boys . but now she does not like them anymore and this is when i started to like her. but now its just so boring to talk to her because I would usually talk about her and those boys. More Details i also pretty much hung out with her every day at nutrition and lunch. It was like i was attached to her. So yeah to wrap it up in a nut shell what can i do to stop being so boring and make me look more like an lively person ? Extra Info i play piano and she play cello so maybe we can do the chopin cello sonata one day :) any more info ask !
