I need advice:

I have, I believe an extremely unique situation here. Let’s start from the beginning. There is a girl I like, that I have liked ever since I met her, about four years ago. The first two years, I was a complete ass. I had no idea what I was doing, she hated me, and I was lost. Then, I got beyond being a immature idiotic middle schooler and have completely cleaned up my act for highschool. Now, we talk all the time. I know roughly what she says that she thinks of me, through friends and such, which is that I used to be super annoying but that I’m not now. She also says that we are friends, but not close friends, which means I’ve not been friend zoned (yet). Also, I told her that I used to like her 2 years ago and she was chill with it, and let it go. Now, we talk everyday at school, not too too much granted, but other than that we only text, and we only usually text about school. Sometimes we talk about other things, but I always have to start those conversations, but I also know that she is shy and not particularly comfortable with asking such although simple questions and usually waits for others to ask her. We have plenty in common, (same opinions, like the some of same music here’s a lot more I just can’t describe it all), and we get along well. However, we have never really shared many personal moments with each other. There was one time recently where I was depressed, ironically about this subject, and was texting her about it (obviously without letting her know it was about her) and she was extremely sympathetic trying to pick me up and such, and we had a relatively deep conversation, although it was all over damed text message, as most of our communication is done: we either talk at school or text, never call. However, I know that if she needed solace that she would never come to me, as she has many other close friends that she would rather go to, and I simply shared my thoughts with her to show her I’m actually not a hardass as she used to years to think I was, and to get rid of hat stigma. SO! What I need to know is does she like me (or do I have a chance) and should I continue to bother trying to win her, or should I just be her friend and try to be a close friend to which many of you will say “no why would you get friend zoned” but in all honesty I respect her enough and like her enough that I just want to be able to be there for her when she is down or needs help and to be good friends, at the very least. Also, if you guys have any ideas about how I could become closer friends with with her, that would be great. Thanks!
