a confusing love..., any help welcomed thanks Options

[31miracles]

There's this girl that I liked for a while now. We are pretty good friends. I know for sure she USED to like me. Everyone thought that we were a couple but I never asked her out. I was stupid and never realized that she indeed liked me. I thought we were just really good friends, and that she would never go out with me. I finally got over the fear of rejection and realized how important she is to me, but I'm afraid that her feelings for me are gone.

Just before I went on vacation, it slipped out that I indeed do like her. We went to see a movie, and I didn't act so smooth.

The I went on a 6 weeks out of the U.S. vacation. It killed me that the last impression I left wasn't so good. And I had to wait a whole 6 weeks to see her again. During my vacation, we talked online. Everytime she was the first to IM, so I thought she liked me too. I sent her a box of chocolates. Then I sent her a love letter (which I thought was a work of art) a week later.

I had the perfect plan to ask her out when I returned from my vacation. I was going to throw rocks at her window the second I got back to give her flowers and to tell her I missed her. I threw rocks at her window, but just my luck I couldn't wake her up. They make it look so easy in the movies.

The next day I asked her to come over and watch a movie, but she said she had to go to the mall.

The next night she gets her friend to call me at 8 at night to go over to her house to watch a movie or something. I was tired, because I had not yet adjusted the 12 hour time difference. I was sleeping, and when my mom handed me the phone. I didn't even remember my mom giving me the phone, so I'm not sure if I said anything. So there's a chance that she thought I hung up or something.

Two days later I wanted to take her to dinner, but she said she had to "buy school supplies and finish summer reading". I did not buy this excuse. Who buys school supplies at night and she still had 3 days before school started.

I started to realize that she might be trying to reject me go nicely. But for some reason she still keeps on starting conversations with me online.

With my unsmoothness and some pretty bad luck, I'm afraid I messed up my chance. I'm not really sure if she likes me or not. The sense in me tells me that she's rejecting me nicely, but something deep down tells me I have a chance.

I love her more than words can describe. I do know that I will not be able to truely love another girl during my high school years(I'm in 10th grade).

Should I keep on trying and risk our friendship or should I just back off?
Does she like me or is she nicely rejecting me?
What should I do?
Do I have a chance?

thanks for the help and sorry that was so so long
