<human>: Give me the gist of the text in a nutshell

Throwaway because she browses reddit. There's quite a bit of background to this but I'll do my best to avoid a wall of text.

I first met this girl my freshmen year of college about two years ago, where we shared classes together the first semester. We got to know each other relatively well and exchanged numbers, mostly for school related business. However we soon started hanging out more often, became friends on facebook, and became more casual with texts to the point where I developed a huge crush on her. I learned over the course of the semester that she had a boyfriend back in her home state but I knew better than to interfere so I continued our friendship until she ended up transferring at the end of the semester to another university in her home state.

At this point I practically forgot about her and didn't speak to her for about a year until facebook reminded me her birthday was coming up. Not wanting to conform to the usual facebook posts, I texted her in February because I'd saved her number and she actually replied back, thanking me. What happened next, I didn't expect. We've been texting ever since.

She asked me how I'd been, how my classes were coming, interests, and basically how life was. These conversations have been going on since February and while its been enjoyable, its been near torture because its brought up all the old feelings and the crush has resumed. She's texted me pictures of herself, started conversations, and casually mentioned once or twice that she'd broken up with her boyfriend. These are things no other girl in my entire life has ever shared with me. I'm not sure she is aware of my feelings for her.

Yes, I know I'm a bit of wuss for not admitting anything to her but the fact that she lives in another state and is unlikely to visit causes me to rethink everything every time. What I am looking to get out of this post is whether to just admit my feelings to her, or to slowly let this relationship slowly float away. Every single day that goes by is another day that the crush worsens.
<bot>: Texting with a crush in another state who is probably unaware of my feelings. Do I admit everything or just let this one slide because we are unlikely to see each other?
