I apologize for the wall of text....

So after ready everyone else's story, I've decided to post my own troubling story. So I am a 16 year old male, a Junior in High School. (Junior year is almost over ^_^) My best friend is currently 18 and a Senior about to graduate. Well, last year a beautiful, shy girl transferred to our school from the neighboring city. I'll refer to the girl as K, I was love-struck by K the moment I saw her and I began talking to her and discovering she had all the traits I dreamed of in a girl, or so I thought. My best friend is in a popular local band, is quite attractive, and is athletic in Track and get very good grades. Well much to my dismay, Best Friend and K began dating and the three of us became close friends over that year. However, I always had her still in mind, I was going to be with her no matter what I had to do. After a year, Best Friend dumped K suddenly, I was the crutch that brought her back off her feet. I told Best Friend I would never be a rebound and I began dating K about 4 months after their breakup. It was incredible, it was like a dream I never wanted to wake up from. We we're only together for a month and she dumped me. She said she just wanted things to go back to the way they were, she was one of my closest friends, I then seen what I did wrong. I tried so hard to get back together with K but she shot me down every time...he was still on her mind for some goddamn reason. I love my best friend like a brother but I want to murder him for stealing the heart of my "dream girl" and then toying with it. It was so obvious she still cared for my Best Friend but I destroyed my only chance I would ever have with my dream girl. A while later, Best Friend and K got back together and have been dating on off for the majority of this school year. K was like a best friend to me before she dumped me, now whenever I look at her I am filled with a strange mix of Love and Hate, whenever she speaks a word to me I shoot her an evil eye and give her a one word answer. Most of my friends as Seniors that will be gone next year...including my Best Friend, I will be left with the very few friends I have left for my final year of school, K being one of them. I wish this woman would leave my life and never come back, she sees my Best Friend as this night in shining armor even though he constantly breaks her heart and then pulls her back up to push her down again. I can't take it anymore....I love her, I hate her....I wish she would just leave my life, having to see her everyday, it's killing me. Sorry for giving a life story but I need to vent and any advice would be greatly welcomed.
