failure of second chance

[OhioLaw1987]

If you've read my posts from the end of march....we got back together. Don't ask me why, I am not entirely sure why I ran so fast back into something so toxic. It was really great being back together, but then we left school for the summer and she went back to her home out of state. The first two weeks she was calling me many times a day, saying she loved me, wanted to get married, convinced me to buy a $600 plane ticket to come see her. Suddenly, a few days later, she needed "space." This entailed her not speaking to me for 5 days, despite me sending a single text each day (after the third day) saying "how are things?" Now, the whole space discussion, it was made clear we werent fighting or breaking up. She just was busy. But I still think 5 days of not saying a word to me after all that emotional intensity was a bit odd. It started to make me weary, in light of our past issues. This turned into a big fight, where all the blame was put on my for being "impulsive" and "unstable." We didnt talk for a week. She then called me to tell me she didnt want a relationship, and needed time to work on herself, but that she loved me still and wanted us to work it out in the future. Several days later, she told me she didnt know if she loved me. Then I learned she was going to see an ex-boyfriend in two weeks. She then informed me she is seeing someone else. I got a bit upset, because it felt like i was simply replaced and was a place holder She can date whomever, and do whatever she wants, but it still hurts. She claims now that i am simply not the right man for her. She says she has a significant part of her that still loves me, but that I am just not right, and that its more cruel for her to be with me when I make her unhappy because she thinks im immature (why, i dont know, she refused to explain further). This all occurred in a time frame of two weeks. I then was informed by a mutual friend that she has told people she was never attracted to me, and that I was a mistake. She has told me that if I cannot be there for her as her friend, then I am immature and "full of hate." I got really upset and blew up on her a bit, and she tells me I am a jerk and a dickhead and that she forgives me for it, but that I am just not a good match for her and its all my own doing. I believe the ONLY possible course of action at this point is to do what I should have done from the get go and just really do whatever I can to get this person out of my life. I want brutal honesty from anyone who will give it! Where have i been wrong, is she twisting this on me, and what should I expect in the future?
