He blocked me by saying we don’t have future I only asked for friendship?

So we both were good friends on fb and suddenly he blocked me one day by saying we don’t have a future ahead. I tried to stop him but he continued saying its good for our future. He said continuous chatting will make our future hard. I asked his bestie for helped but he told him also to stop talking to me and “ she will understand what i did is good for future”. I just asked for friendship nothing else but still he blocked me.
