TEN POINTS BEST ANSWER!! get her to hangout?

Invite her to something that a co-ed group of your friends is doing. At the end, leave at the same time she does. Then ask if she wants to hang out right then and there. Make sure you have something planned to do though. Just walking around works fine, but don't be indecisive, have options ready. Leaving at the same time will show her you like her right there. When you go out to your cars it will create a situation in which you can finally talk to her alone. During the party you may want to jokingly suggest doing something afterward and then bring it up in a more "Why not? Let's do it!" sense when the opportunity to actually do it presents itself.
