maintain your distance as I mentioned and allow her to pursue,
if she wants to be with you, she really will do all the work that's required, she'll be the one trying to convince you, she'll be the one making it easy on you, she'll have the cheery attitude, she'll try to put her best foot forward, she'll present herself in an attractive way, she will work for it.

If you make it easy for her, she won't have to put in the effort which means it's too easy and has no real value, we are used to working for things that have value. YOU have value.

Maintain your distance like I said, let her pursue you, she talk relationship talk, you won't bring it up whatsoever (you heard me right?), you can answer her calls but take your time, in fact let her call a few times, just tell her you were busy or your cell was in your jacket pocket or in another room charging, don't respond to the texts within 5 min., wait a bit, take your time.

Think about it, waiting for her texts made you anxious, "why isn't she replying, it's been xx minutes already?!" Do you see how it makes you feel to wait? That is reality. Reality works, use reality.
