Lost Stubborn Friend :-(

I have a friend with 4 years good relationship. He used to be my customer and like me lots. 

I had my principle to keep all friends are friends, never over step the line. However, we met in China in again in Shanghai in Nov, 2010. He want me to live in same hotel and had business meeting later on, I refused it and found a hotel in another place which was far away from his. 

He was angry so much with me by sending me text message which means he would never to see me again! 

I lost friend and half million orders! 

I know our relationship had been cut forever now as he is stubborn Iris guy which 15 years older than me!
