Although everyone seems to have pretty sound advice i think one thing to add is not to directly hit on her via text if you want her to respond to you via text... Be flirty with wording and questions that challenge her to respond. Ultimately you best solution via text is to look up t-mal's text thread bible for do's and don'ts. As to when the next time you see her in person, ignore your mistake or flaw that you showed. Reframe yourself to being interesting showing motive to have a good time and crack jokes. Don't make it about dating her unless you want a clear direct answer right away.
