My best friend hates me and he is not talking to me i don't know what i did wrong what should i do?
The best thing to do is to try to talk to him first and ask what the problem is. If getting to him doesn't succeed, you can write it in paper or send a friend to communicate to him. You should be able to resolve it since you two are best friends.
nothing lasts... the sooner you learn to accept it, the sooner you will come to terms.
talk to him tell him why is he acting that way:)
ask why hes mad at you then suggest doing something to cheer him up
