I am in love with my best friend.

I told him how I felt and he is telling me the friendship is over. I feel so stupid. I feel so hurt. I never felt this hurt. It took alot for me to tell him how I felt. It wasn’t easy. He acted like I said something horrible. That is the worst feeling in the world. I can’t handle this pain. I don’t know what to do. He won’t answer my calls or anything. help? I don’t want to lose him as a friend.
