5) Ask her out. Just you and her. None of the rest of your gang. Nobody else. Yes, it's a date. It could be a movie, it could be a drink at a coffee place, or if you're really confident, it could be dinner at a nice restaurant. Don't treat it as if it's a big deal, as if by saying yes she'll be making a big commitment to you. Keep this in mind if she's reluctant - say, "Hey, it's just a movie/coffee/dinner, I'm not asking you to marry me laa."
