I dont know what to think!

THIS SITUATION IS DRIVING ME CRAZY, AS YOU WILL SEE HAHA, I just need advice on what this girl is doing and where to take this!! I am an early 20s male, and recently I had been talking to an old High School flame. We dated for about 5 months or so without any serious commitment and or sex ( might I add that this girl was viewed as extrememly open to sexual activity in high school, and i was a different type than what she usual was dating), talking every day and dating often. During this time period it was our senior year and we both had an intense attraction it seemed ( her telling me she " thought" she loved me and asked me to be with her, however rescinded when the thought of me going away to college was thought of). We would argue occasionally, over me getting angry at her for blowing me off occasionally and sometimes over reacting, however it never really was the influencing factor.As I left for school we continued to talk however we slowed because of the difficulty, but we still would date whenever I would come home. Eventually we fizzled out due to the fact she wouldnt commit to going out as much, however she was not seeing anyone. Eventually we completely stopped talking and " seperated" on mutual, yet undiscussed terms. A year passed and I began talking to other women, as well as she talked to other men. Eventually I found she started dating a male older than her in a more serious manner for about the same period and then it ended on terms I am unaware of. As time went on I still had the feelings for her on my mind and made an attempt to talk by wishing her a happy birthday and we would comminicate sparingly, like one time a month for a couple months, until I ran into her while I was out at a bar, to which she saw me and began texting me and telling me she needed me in her life and I looked great. I was taken a back by this and figured she was just intoxicated and didnt say much other than we should get together and didnt take much from it being that I thought she was intoxicated. Well as time went on, every weekend she would text me where she was that night without anything else, and i would sometimes respond, sometimes not, however never committing to go to the location. Eventually this wore me down and I asked her to come hang out with me and she never would committ and or respond as well. After that, I eliminated communication once again, and about a couple weeks later she told me to visit her at work, to which I responded by why would i do that? and she said nm. I felt wrong by doing this so I told her that I felt like i didnt really feel i was right by that and said i would be ok with seeing her the following weekend, and thats when the location texts began again. Sure enough, I gave in and asked her to hang out one weekend and she said she would get back to me after work, which she never did till later in the night at around 1 in the mourning asking my location. I told her i wasnt around and was upset she waited so long, and she began to tell me how much she missed me and how she wished we never stopped talking, calling me baby and all that. Again, thinking it was the booze, i took not much from it, however the next day i got a hold of her to make sure she made it home alright and she said yes and began to initiate conversation. I asked her to hang out that evening and she asked me what i was doing and i told her i wasnt sure, probably not very much and wanted to hang out and she said she would let me know. Never did. The next day i called her out asking if she just wanted attention from me and she flipped out saying she didnt need attention from a cocky sob and that she had a bad night. I stopped talking and again felt like maybe i was too pushy and told her a couple days later that i was in the wrong by approaching it the way i did and told her i had feelings still, to which there was no response. A couple more days later and i called leaving a voicemail, again stating my approach was wrong and i wanted her in my life. She responded saying it was very nice and that she was happy i did that and everything was ok, and i asked her once again to allow me the chance to take her out and hang out, which she didnt respond too and later which responding saying she was at a funeral and would get back to me. Never did, so later in the night i said i hope your doing ok, i dont wanna push you or anything and maybe it wasnt such a good idea and got the point, then she said she definitly wanted to hang out and would like for me to take her out, so we made plans for the following monday. I call her on sunday at around 9pm and everything was still good, texting her later saying i was very happy to be able to hang out and excited to see her. Then monday rolls around and 3 hours before i was suppose to get her, she said she wasnt going to be able to make it and she was really sorry. I said i wished she would have told me and she said sorry her friend needed her help. I then said its fine she had to do what she needed to do, and that i was really confused what she wanted from me and to let me know, with no response, and she said she was helping her friend pack. I told her i wasnt trying to be intrusive but i was upset by this and she told me she didnt want a boyfriend, didnt want stress, or anything like it, and i asked why she didnt just tell me, and she said she didnt kno that i wanted to date or whatever else i was trying to do. I got extremely angry by this, and told her i understood that but wished she would give me a chance and to not rush into things, just wanted to hang out and that i still had extremely strong feelings for her and she did not respond. So i told her i understood the point and that the idea i was getting from her was that i was just going to be another **** for her, and she got extremely mad, as expected, and told me to not talk to her anymore. I DO NOT UNDERSTAND THIS SITUATION AT ALL! I understand the point now, but can someone please tell me what I might have done wrong, was I at fault? Or was this something out of my reach?? As much as this is an odd situation, I still continue to have feelings for this girl and at this point I am ready to move on completely being that i let her kno all of my feelings, but i just dont understand it
