Me and my girlfriend were in a long distance relationship and she cheated? i know this is long,please read it?

May has began and everything has been going great until later on in the month I looked at her myspace friend and andrew posted a status of the date they got together (which was the date he posted it) and the mood at get name by it with the heart icon and when I saw that, my heart sunk, I cried and my heart was hurt. I asked her about and she said that it was nothing and I'm being rediculous. I agreed with her and I calmed down and she said not to worry about it. Andrew kept posting love statuses everyday of my girlfriend and I kept telling her about it and she said to ignore it. I tried to and I couldn't, then later on in during the summer. Andrew posted a picture of him and my girlfriend kissing..omg I like stopped breathing, it shattered me inside and I was so mad and sad that I started cussing at my girlfriend about it (who wouldn't get mad? The feeling of getting lied to, especially in a situation like this). She said the picture is from along time ago and I asked her why she never mentioned andrew way before (because she told me about all her ex's) but she didn't tell me about him. I didn't believe her, I was so broken. A girl that I fell deeply for, we had thanksgiving, Christmas, new years, valentines day, Easter, and her birthday. We had so many plans together. I wanted our relationship to last forever, and she did too. I was texting her and andrew had her phone and told me not to text her anymore, and that I will always be lonely. It's all andrews fault, he set me off. He had no buisness in bugging into me and by girlfriends buisness. All I can say is, I tried my best and I know she's never coming back after all the love I gave to her, I thought she would be mine. I am depressed, I'm suffering in pain. She was 14 and I was 16 when we got together and now she's 15 and I'm 17. We only live a hour or two away. I don't know wat to do? i havent been on myspace in a long time because i'll tend to look at her profile. i didnt ask for this. i miss her very much though, we havent talked in a while. its just wierd that she is with someone else now. after everything we had, the holidays and us together. im so sad. i hope she still thinks about me, u think she still does and wonders why this happened? everytime i think of andrew, i seriously grind my teeth. i hate him! he bows down to me in every way. i want him to kiss my feet and apologize to me. its wierd not talking to her anymore, i still think of her. i need good advice, please. im suffering. do you think she will regret not being with with me even though i got mad at her? shes giving all her love to him and not me...hes living my life. i cant even think, i cant eat, im tired all the time, and im lazy. i cant believe she has done this to me. i spent 10 months of our relationship making her happy and talking and love. it feels like i wasted 10 months of my life. i told her that i am gonna break up with her when i had to much of this because of the statuses and this was ll tearing me apart. when i told her that i was leaving her, she called me crying, i was kinda suprise like this. (this was before our final break up)

i woulda never cheated on her, i had too many feelings for her, i still think of her. i want them to both burn in hell though, they can rot there for eternity. i dont even know wat to do if i see her. we had a date planned, and those seats r suppose to be tooken by us):

im all outa energy, forget it, i hate everything. she has been cheated on in the past and i felt really bad, so i picked her up from the dirt that her ex left her in and loved her and later and she turns around and cheats on me? i woulda never cheated in her, she was my god giving life
