heres some advice, if you really want to be around her, be her friend and hang out with her. there's not a big difference between normal friend and romantic friend in middle school except for you willingly hug a girlfriend. but middle school has pussies so they dont kiss.
If you still like eachother in high school then you can actually have some progress.
I realized that having them as a friend is better than ruining it at early ages by trying to make it romantic. i have a friend whom i've had a crush on, and we're just friends. (Although i think one of my bastard other friends blurted that i had that crush when i wasn't looking, (facebook))
today we hung out like any old friend and i had just as much fun except for the sinking feeling i get when i'm near my crush. we had the same solo in band, and were sent to practice rooms, and she came into my room and decided to practice with me. (I noticed i've got a WHOLE LOT of friends that are girls, more than the guys, but none of them like me that i know of.)
The entire time she practiced i was grinning like a fool and i got a warm feeling that wasn't pee, mixed with the sinking feeling.
She tends to try and be rough like my friends are with me, (for example, she'll jokingly punch me in the gut, she'll tickle me to make my voice crack, and she likes to talk to me.) Just hang out when you're in middle school. going out and hanging out in middle school are barely different, so i suggest not making your friendship awkward or end.
