Then just be friends and leave it at that.
girl likes me and i don't like her back, she is nice but also really awkward?
Tell her that straight to her face...that should do. Lol
Did she ever said she likes you?
just tell her that you would rather be friends.
What's wrong with her back? Is it hairy?
Don't judge others lest you want to be judged. No body out here is perfect and neither are you as you will have faults, we all do but look for the real beauty inside this girl and try to be friends as all relationship begin as good friends first so don't sweat the small stuff as we all change in many ways as a Teenager and you may be surprised at her and vice versa so go for being friends here. Good luck
I think its not a big problem in relationship. Just ignore it!
