Well about a month ago I fell out with my best friend. We were just arguing about the silliest things and that. It was a spur of the moment thing and i decided i didn't want to speak to him/be friends anymore, he said he felt the same. And since then, we haven't talked at all. He hates me for some reason. But since we fell out, he has really changed, he's so different as to what he was like before, and it's scary to see someone change so much. He always ignores me in school and I always get the feeling he's talking about me. We were such great friends before, I've known him nearly all my life and I'm upset about losing a friend who I've known for so long. We used to have such a great time, but now it's not the same

all my other friends are great, but I really want my best friend back. I just want it to go back to the way it was before.Does anyone have any advice?
