Please read the entire story before posting. I will try to keep it concise, yet detailed enough to get a good idea of what has been going on.

So, I noticed this girl start attending the same church as me about one year ago, but I also noticed she was somewhat quiet and usually hung around 2 or 3 girl friends, hardly talking to or noticing anybody else. I thought she was pretty and finally found an opportunity to talk to her last May (so about 8 months ago). We hit it off quite well as we had quite a few things in common and therefore a lot to talk about. I had known her socially for about a week before asking her out. She accepted and we ended up going on 3 dates in about a month's time. Here is how they went:

First date: I continued to notice that she is somewhat socially awkward, very smart, and although I've never found out for sure, I'm confident that she has rarely if ever dated that much (we are both in our mid-20s). She is a college grad who is extremely focused on getting accepted to a specific grad school program that will require her to leave the state (she is from here, as am I). Nonetheless, I enjoyed myself, yet she was very hard to read and I couldn't tell if she was having a good time. She wanted to go home fairly early, though I don't think it was to get away from me. We talked awhile in front of her house when I dropped her off, and she expressed interest in a second date.

Second date: She texted me about 2 weeks later wondering if I would like to go out again, as she had an idea. We ended up going on an afternoon date and it went really well. She seemed to enjoy herself and I ended up asking her if she wanted to do something later the next week. She tentatively agreed, but said she would have to check her schedule.

Third date: She ended up cancelling the third date to spend the evening with her dad, but said we should talk at church about when we could reschedule. I approached her that Sunday, and she acted very distant and claimed it would be hard to find another time to go out, but she did get back to me later in the week and we went out that Friday. Again, she wanted to get home early, and I mentioned the possibility of another date. She was leaving the country in about 2 weeks for a month long humanitarian campaign (she's WAY into that stuff), and I said I wanted to go out once more before she left. She said she couldn't think of any possible day that she would be free, and date#3 ended up being our last one up to this point.

While she was away, I started emailing her and we wrote back and forth about twice a week. Some of her emails were very short, but others were fairly long and enthusiastic. After her month away, she returned home and I jumped the gun a little, trying to hang out with her a few days after she got back and when she said she had plans, I mentioned going out again the next week. She once again said to talk to her at church. I did so and she was once again distant and hard to talk to. She said she had to retake some school courses and start interviewing for grad school and was very busy for the next 4 months. I let it go and stopped talking to/texting her for about a month. At this point, it was about October and after starting to pursue other girls and avoiding this one, she approached me at church and began talking. She said how great it was to talk to me again, etc. etc. I fell under her spell and asked if she wanted to go to an upcoming film release in November with me and friends. I encouraged her to bring her own friends to make it seem less like a date. We began talking and texting on a regular basis again until the movie, where she brought a girl and a mentally challenged guy (remember, she is into humanitarian/service efforts). I had bought the reserved tickets for her and her friends and said they could pay me back at a later time. I made sure she had the seat next to mine. She walked into the theater, saw where we were, and asked her mentally challenged friend if he wanted to sit closer to the middle, thus placing him between us. I was embarrassed and once again decided to avoid her. She had me go to her house a few days later so she could pay me back. She invited me in to talk, but I was still a little upset and didn't stay long.

Avoiding her again lasted another month, until last month when she emailed me asking if I would do a favor for her. She needed a letter translated into another language that I speak, as she had to send some information to someone in that country. I went ahead and did it, as it was not a problem for me, and she mentioned that she owed me for it. I was feeling kind of sarcastic/sassy, and also wanted to test the waters, so I suggested a backrub as payment (kind of in a joking manner). She emailed back and said "Haha! I could do that, and I definitely will pay you back. This week is busy but maybe after that..."

I didn't see/hear from her for a few days and after about a week, I texted asking if she heard back about that letter I worked on. She said no, but she needed me to translate more questions. I did so, and asked about that backrub, but mentioned she could pay me back anyway she wants (hoping it would lead to another date). She said she was leaving town the following week and felt bad about owing me for this long, but she would definitely make it up to me. I said I wanted to do something with her again and we could work it out when she got back. She agreed. I translated the 2nd letter and saw her the next day. We talked for awhile, catching up on things. She seemed more enthusiastic than usual and it was one of those situations where we would say goodbye, about to part ways, then both just stand there wanting to talk more. She would also pause and stare at me for long periods of time. I started thinking that this isn't dead, but I texted her later in the week wishing her luck on her trip and that she deserved to have a good time. I phrased it in a way that showed I'm still interested. No response. Probably won't get one at this point.

That is where this stands. Keep in mind that it's very likely she has never had much to do with romance/dating. I've been afraid to even hold her hand as she just seems like she's never been into that, and shows NO signs, even at the beginning of this. She is still hellbent on grad school, and hopes to leave the state in the summer. I am extremely attracted to her, love talking to her (when she's open), and can't stop thinking about her. It's driving me nuts. I'd like to at least date her until she moves. What should I do? Should I wait on her to act? Should I push for another date? Or should I move on? I've dated other girls during this time, but I can't get over her.
