One thing that I think is important is that, every 2 weeks or so, she will text something to the effect of "You've disappeared..." or "You don't want to see me anymore? " or "You're horrible at texting back!".
In other words, periods of absence (with her noticing).
Or if you do text she should write back within 1 minute something like "Wow, never thought I'd hear from you again.".
When she is interested there should be a few multiple-part texts (over 140 characters) from her, including at least one 3 part message (think of the girls who liked you). And she'll out-text you in terms of both the size and the number of messages, redundantly texting things like "What????" in one message and then "Explain." in another reply to your message.
Keep it that way. Randomly let the conversation end with her having sent the last message. Then when you do see her, make sure it's way more fun than the average guy would be.
