Ok, so I met this beautiful girl during a competition about a month ago and I thought we really clicked. I'm pretty short (like 5' 4") and she’s even shorter than me (like 5' 0") which makes me a bit more confident I guess. We have a lot in common and have been talking for a while. I thought there might have been a chance to maybe date her but I was trying to establish a friendship first. She lives about 45 minutes from me and I used to go and watch her games all the time and talk with her as much as possible. However, I began talking to he ex-boyfriend (who is a good friend of mine) and apparently she is seeing someone else already. But the kid she’s seeing treats her like crap (and according to her ex, i’m better looking than he is) yet she doesn’t break up with him. So a few nights ago, i’m talking to her ex and he says "hey, i’m talking with her right now, what do you want to know?" so I said I wanted him to kind of see what she thinks about me. He said that she said she’s not interested because 1. She’s with someone right now and 2. I’m going off to college and she’s a junior in high school. Long story short, he told her a lot of things that he shouldn’t have and now she doesn’t want me to come to all her games anymore and she was going to go to prom with me (even though she was seeing someone else) but now she doesn’t want to. She told me herself that if she wasn’t seeing anyone, the only reason she wouldn’t be interested was because I was going to college. However, she said she still wants to be friends and that things can go back to almost normal now that we both are on the same page. Things are so much different now though, we hardly talk anymore and when we do, it almost feels strained. It just kills me because I really like her and I feel like I destroyed our relationship. What can I do to get her to change her mind?

*edit* she’s also leaving for florida for softball tomorrow at 6pm. I asked her if she had any free time so we could hang out before she left and she said she had a lot of stuff to do. (i don’t think she’s lying, she’s missing a lot of work while she’s gone). But here’s the thing, I want to leave her something on her car or something while she’s at work. Is this a good idea and if so, what should I leave. And one more thing, we will be at the same competition together son and she is celebrating her b-day and I am invited. I want to get her something but I don’t know what. She’s a big car fan (so am i) and she loves subaru sti's and I was wondering whether it would be a good idea to get her like a big die cast model of one since she told me how much she loves them and wants one? (like the pre-assembled ones you can buy at sharper image and other places) I don’t want to get her something that her bf should be getting her but I want to get her something that will make her think of me when she sees it.
