Honestly I would forget her and move on and look for someone better. It sounds like she may be playing you or too confused to make up her mind and will end up hurting both of you. If you keep bugging her she may just get wierded out and tell you to keep away from her. I don't know exactly how well you know her but doesn't sound like a lot. As for future dating. It's ok to ask a person out on a date even if you don't know them that well. That's what dates are for.
