Girl ignores me after I asked her out

Hey, I'm having a problem that's making me crazy. I'm 15 years old, just started Swedish "high school". I asked this girl out, and she said yes, and said she would tell me when she wanted to go out. but she never told me any thing and now 2 week have gone by. We always said hello when we saw each other in school before (we have been in the same class for 5 years), but now she doesn't even look at me even if I'm right next to her.

I've liked since the first time I saw her, but I had only talked to her like 5 times in 5 years. When I started "highschool" I got the courage to talk to her and ask her out.

I'm asking you girls why she acts like this and what you think I should do?!

I also had boy friend like 3 months ago, but she broke up with him because he was "stupid". he talks to her every day, but they're not back together and he's not the kind of guy who would do something so stupid what it would take 3 months or more to get together again. I have this feeling that she doesn't want him any more.

Am I right or paranoid?

Help!
