For the past few weeks, I've been texting this girl (HB9) on a fairly consistent basis; every couple days, I'll either text her or she will contact me. Recently I've noticed that she has been giving me IOI's, but is still usually the one to end the conversation first.
To give you some background, I had one-itis for this girl bad when we met a few years ago. When we hung out, it was all very natural and we developed a strong connection over the course of a few months. Eventually, we had a short fling, but it didn't work out for a multitude of reasons, mainly my neediness. Being an AFC, I took it badly and sulked for a while before finally getting the balls to freeze her out.
It's been well over a year now, and she re-initiated contact about a month or so ago. I've been playing it coy, and limiting my responses in an effort to show her I've changed from my old, needy self. I feel like I've been making progress, but it's been hard for me to maintain attraction since we live 45 minutes apart. (I go to a University, she is about to graduate high school.) With me not being a physical part of her daily life, I can see how it would be easy for her to become disinterested rather quickly.
Here's an example of a text she sent me about a week and a half ago:
Her: Sterling! We need to do something soon! It's been a while since I've had an adventure.
Me: HB9! I'm down for an adventure. We can hang next time I come home, or you can always just come visit me in [my town.]
Her: I've been looking for an awesome reason to go. 
Me: Then look no further!
I'll let you know when something cool comes up. It's been too long.
[end of convo]
Not long after, I told her about an upcoming concert near where I live, and she seemed pretty stoked to go. A couple days before the concert, I texted her and asked if she wanted to meet up and she said she wasn't able to get off work and couldn't make it. Naturally I still went, got drunk, and had an awesome time at the concert.
Still, it troubles me that I'm getting mixed responses from her. In some conversations, she'll drop all sorts of hints, and in others she won't continue the conversation for more than a message or two. I don't know how effective a Freeze Out would be either, since the amount of attention I've been giving her is pretty low - only about 2 conversations a week. Yet if I step-up the amount of attention I give her, I sacrifice my control and run the risk of making her think I am needy. If I can get this girl to meet up with me, it should all be smooth sailing from there. It's just getting there that is proving to be difficult.
I know the attraction is there, I just need someone to tell me how to maintain it - and escalate it into something more tangible.
