Sorry.

I'm really immature.
i'm still resorting to the "i'm pissed so i'm going to do something so you get mad at me just as much as i'm mad at you" thing.
yeah, i cheated on you. but i have been cheating on you since the day we met. I'm in love with someone else, been touched by others. I should've never said yes. I'm sorry i'm so immature; i don't want you.
