Stop fucking around and ask her out. She likes you, you like her. The worst thing you can do is dilly dally and procrastinate. She'll think you're not really interested and move on.
Ask her out as in a date? She said she wants to come with me to a rave this weekend.
Oh, cool. She knows it's a date and doesn't just think you're going as friends right?
Of course.
Awesome. Good luck man.
If you guys haven't kissed yet make sure you go for it while you're there. Don't wait too long to do it.
