You know who you are.
If you don't want to be friends, then that's fine. I understand that I've hurt you. Just know that I will cherish the times that we spent.
I'm a fool for thinking I could fix this with words because I never can. Words are just meaningless sounds and letters thrown together to try and create meaning.
In short, I'm an oblivous, selfish, idiot who doesn't deserve your friendship.
