He is like a brother to me I can't lose him.

How long have you been friends? If you have a lot of history, maybe you can salvage the relationship. Just give it some time. Try to have a heart to heart talk with your friend if possible. If your friend is not open to the idea, wait a while and try again. I hope your truly proves to be a friend.

He's not much of a friend if he hates you for that.
