today after school i was talking with my girlfriend and i was telling her how pretty her green eyes were... then she tells me to stop. that the guilt was eating away at her.. she told me she needed to tell me something. then i ask her wat it was and she didnt tell me. she said she thought she couldnt tell me so then she had written it down.. at this point i thought "maybe its something cute" but i was terrilbly wrong. She had something written down along the lines of - i cheated on you with my ex. i gave into temptation. im sorry. that day we had late start at school i went to his house and did some stuff... i (messed)* up. *a bad word went there.
and then i asked what exactly she did. and she didnt say anything. she told me she was gonna write it down.. so at this point im thinkking "why the hell am i still here?" i knew what she had done with her ex, they did worse things than i ever expireenced. but then again, im still a virgin and i never done anything too intamate. so i got up and left. i went somewhere where i knew she would never think to look for me... i found one of my verrryy trusted friends and i spoke to her about the situation. i felt like dying cuz i really love this girl with all my heart. and i know i didnt do anything at all that would ever offend her or anything... im actualy starting to think maybe its something i didnt do. maybe i didnt relive her sexual tension well enough? im questioning my self worth. My trusted female friend (like my sister, never could be my girlfriend) told me she has no idea what shes doing cuz i am the nicest guy anyone will ever find in a gazillion years/lifetimes. and i believe that. i was nothing but sweet to her. i beleive i was the best boyfriend a girl could ask for, but apparently not.

i really dont know what to do. i know i love her, but will our relationship ever be the same? i think i can maybe possibly let it go... but how could i b sure to trust her. and what if im beggining to become desprate, i dont want her to see me like im desperate. i got no clue what to do. she kinda had a one night stand with him, but in the morning. and i feel ripped apart. i cant talk about it with anyone.

i think she needs to convince me that shes still worth it. when i first became her boyfriend, i told her that i cant take it when someone cheats. ive never cheated. ive never lied. and those are horrible in a relationship. i told her we need trust if we were gonna have a successful relationship... she agreed to that.
i dont know if i could, i mean should move on... i used to think she was the best. i used to admire her. i used to think she was soo amazing. but now... i dont know what to think.
i really need help. i dont know what to do... can anyone please help me? this happend just today and im not sure what to do..

I would move on...
