I'm lost and confused.

I had a strange suspicion that a girl I met back in high school has always had a crush on me. I transferred high schools, and she rode her bike just to see me once. I acted to pretty lame that time. She's a shy girl and laughs a lot at what I say and sneaks peeks at me.

Then, we both went to college. I went to a college far away and she went to a community college. Every time I'm back in town, she would spend time with me (either alone or with a bunch of mutual friends). One time, she hugged me once she saw me, and another time she linked arms with me cause I said I was cold. Sometimes she would hang her arm around her shoulder. I never returned the IOI cause I was a stupid prick.

I'm starting to admire her admiration for me, in truth, I like her. The problem is that she has always had a "boyfriend". I became what she would say a "close" friend, even though I only talk to her a couple times a month, she would spill out all her problems with her boyfriend.

For the last couple months, she no longer talks much about her boyfriend even though they are "together" even though we still see each other every time I'm back in town.

I'm back in town for the weekend and she wanted to meet up. Even though I was available during the whole weekend, I told her I was only available today - which she had made prior plans, and she ended up deciding to hang out with me today. We hung out at the mall, ate lunch and watched a movie. Over the last few months, I've began to read PUA stuff so I thought it would be interesting to see if I could put what I've read into reality.

I started with slight kino. No response. She still laughs at what I say. Good. In the movies, I leaned slightly towards her. She sat pretty straight and the physical contact we had was sharing popcorn. Next, she kept texting and looking at her phone throughout the whole time we hanged out. To be honest, I was going to tell her that I liked her but her performance today made me unsure of just how much she is attracted to me.

I'm lost. Am I just a close friend? What the hell am I to her?
