When something unfortunate happens in my life the first person I want to talk to is...

The first person I want to talk to when anything significant happens is him. He always listens to what I have to say and he always does everything he can to make me feel better. He's the only person that's ever held me while I cried. But recently I decided to tell him how I feel about him and he doesn't feel the same. I don't know what that means for our friendship moving forward but I need him. I don't have anyone else to tell about losing a friend, or getting straight A's. He's my best friend. I just need him to stay in my life, one way or the other.
