I think eventually in life you grow out of "best friends". There are friends, some you like more than others, but every time I've had a friend who I've called my best, it's ended with betrayal, and not from me. From them. I'm not perfect, I know, but really. One time, my "best friend" wanted to go to Texas to see some friends, and asked me to go with her. I figured why not and I went. Well, when we were there, she ditched me the entire weekend, so I was alone. I tried to talk to her about it, and she told me that she only asked me because she couldn't go alone. Apparently she didn't care about me at all, so we stopped being friends.
