Should I end this friendship?

my best friend Alison, has been my best friend since like 1st grade. But I feel she is always competing with me in everything I do! from clothes to hair and the worst is school! she always asks me what I got on my test, and tries to get up and get a...

tissue and when she comes back to sit down, she'll try to get a peek at my test to see what I got. And she thinks I don't know what shes doing! I have plenty of other friends. I don't even know why shes still my friends. She purposely does things to make me seem dumb. like me and her will be walking and shell slow down so I'll walk ahead by myself. I MEAN HOW GAY IS THAT! she seems so childish. and she got a pair of coach sneakers and you cud soo tell she was trying to show them off. the kept tying them in front of me, and say "ugh these stupid shoes" so I would look at them. but I kept looking away. she acts so queer sometimes ! ughh I don't know what I should do. I need honest answers. THANKKK U =)

Have you ever thought, maybe she's not trying to make you look dumb, Maybe she's trying to impress you or showoff.
I would giver her a chance, it doesn't sound like she's doing anything all that bad.

what mandyloo said is quite possible, but so is what you are saying.
Perhaps you should confront her on the way she acts. Tell her if she can't come down and float back down to earth then you would prefer it if she found a new friend.
be honest but try not to hurt her maybe she is just triing to fit in with you and she thinks what shes doing is making her seem more popular in your eyes.
talk to her, the longer you wait the more you'll have to put up with it.
oh and for her slowing down while your walking fast just play the same game she is.
if she slows down and your ahead of her when you turn around give her the finger and go talk to another friend lol.
she'll get the point that it's babyish soon or later.

Yeah... I agree with Mandy, I don't think she is trying to make you feel stupid. If she was she would shoot you down or say something nice about herself and then question you. Maybe she is envious of you and wants you to notice her, maybe if you boost her confidence and say a few nice things to her she will stop acting so weird and act like a friend, right now she seems like she has a low self esteem, just be there for her.
