Guy best friend won't talk to me anymore

He started developing feelings for me and started getting super pushy about them.. It was making me super uncomfortable because I only see him as a friend and I emphasized that a lot. Yesterday he got me really mad because he kept asking why I wouldn't date him, then would tell me to stop being a "softy" & I need to get over a situation I'm going through. 
I ended up telling him that I only date Asian  guys, which is true & he knew that all along (I'm Salvadorian and I've dated other races I just prefer Asians more) I don't know if that pissed him off, I tried talking to him about how I'm happy he's my best friend but he never got it.. 
Was I too harsh? 
Should I try fixing our friendship or just let it go?
