I know that most of you generally prescribe to the principle of moving on when a girl doesn't return texts and/or calls, but I wanted to hear from some of the guys who can rekindle interest.

Here's my story:

I used to be a pretty successful PUA in LA. I had to stop going out to finish up my doctorate and then student loans kicked in so I was financially struggling. Anyway, I recently moved to a major university town in the midwest.

Met this beautiful girl at this club - she approached me. Let's call her Katie. She was a bit younger than me (20) so I was pretty disinterested. I gave her my number and told me to call me, but if she was going to call, she should do it tomorrow or else she never will.
She texts me and we exchange texts. Set up a date - she suggests a Thursday (which happened to be Valentine's day). We went out and... she was actually smart, although like all hot girls has to give off the ditzy/airhead attitude at times. Needless to say, I went from indifferent to liking her and we had fun. I did not kiss close as I generally like to save that for the second date. Anyway, at the end she said, "we need to hang out again." For what it's worth, I know that I made some mistakes on the date with no seeding, investment, kino, etc etc...

So I text her Saturday night (mistake #1) and ask her to guess what I'm watching.
She texts back and guesses the show (Big bang theory, which we both love).
Then I text her again and say, so when can I see you again (mistake #2).
No answer.

I text her again on Tuesday, asking her how her exam went
She responds a few hours later saying that she had two of them and she's totally exhausted.
Now I'm starting to feel the distance.

Wednesday evening I return her text (we were going to get hit hard with snow, so the university cancelled classes for that Thursday) and say, "classes are cancelled for tomorrow. Come play with me out in the snow."
She responds around midnight: "Hahaha, I'm going to be sleeping"
The next day I text her around 1:30 pm: "Wake up sleepy head, come out and play with me"
No response.

So I haven't sent her any texts since (almost 2 wks now). So IMO, I have three options:
1. Re-initiate contact via text with something cocky and funny. I'm thinking: Hey I lost my contact list, are you the dorky Katie or the hot Katie? I would follow that up with, "so you're not the one who invited me out on Valentine's day and didn't bring me any chocolate?" or "so you're not the one who kept pretending she was cold just to wear my coat?"
2. "Accidentally" run into her at a club. I was going to go with a group of friends and another girl (Sara) that I'm seeing. She's this beautiful and exotic girl who wants me to go out dancing. So I thought of going with a big group of people to the place where Katie works, bringing Sara and just dance and have fun (I'm a pretty good dancer, which Katie doesn't know, but she loves dancing). I was going to pretty much ignore her, but I'm sure she'll end up seeing me.
3. Let her go. Which I hate as it's like giving up.

What do you guys think?
Any other suggestions?

Thanks
