<human>: Can you give me the gist of the text in a nutshell?

I met her a year ago in person, exchanged numbers, and kept in touch. This past weekend she came into town (from eight states over) and we had a lunch date in her little free time. It went well!

However, anytime in the past year I've tried to be directly flirty, sweet, or what have you - she never really responds. But, she is interested (take my word for it)! Previously, she told me she's waiting until she moves here (in 3 weeks) to get to know me, so I don't think the date we just had counts.

Either way, it's a little frustrating because I know she's had some trust issues in the past. This is demonstrated by a "man fast" she went on (and informed me about so I knew why her communication dropped, temporarily, until I said I'm not doing games). I want her to start opening up, to trust me (she said in the past how genuine I am is scary in a good way), and to stop (I feel) playing texting/calling games - eg: her texts are typically brief, she'll end phone calls early out of the blue - it's like she's running reverse game on me.

She's moving to my town in three weeks, and on the date we agreed to see each other again when she moves. However, a few days after the nice date, a few innocent texts I sent weren't replied with sweetness, and it's getting frustrating.

Any insight, or ideas?
<bot>: Girl, who is interested, is guarded even after talking casually for a long time and having a nice first date. I'm not sure what to do. Advice?
