What's going on?i'm confused..?

The past month I've noticed whenever I'm hanging with my girl-friend I feel really attracted to her and like I just want to make out with her right on the spot...and I'm more happy and giggly and in love acting you could say? also I've noticed her get more clingy and staring at my lips a lot and just not normal best friend acting we could say? and I barely EVER hear her go girly over any guy...when we were younger before puberty she gagaed over zac efron..no one since then(we're 14 now) that was when we were 10..but since? no she even rejected a guy who asked her out last year...I'm Bi I know for sure,but her i'm not quite sure about...does it sound like theres a possibility she is and likes me?help :) thanks..
