Good morning everyone.
I have a call of duty problem!
The problem is... My brother-in-law is playing call of duty with a couple of our friends and me, and at the end of the games, he's always threatening to never play again. What should I do? I enjoy playing call of duty with him, and he enjoys playing call of duty with me. The problem stems from playing with our friends. He gets upset because one of our friends stinks at Call of Duty and always makes us lose the games. My brother-in-law now has set up his Xbox live so that he's hidden to make it, so he doesn't have to play with them.

What should I do??
