He's was at a difficulty situation and faced a failure with some level of humility. I have tried helping him but he's unwilling to discuss his problems, and instead he let himself sink in his problems and got addicted to video-games. As a result, he has brought me some troubles and broke promises on several of our agreements. He is also doing poorly professionally and have no concrete plans to pick himself up. It has been half a year and nothing has improved even though I tried helping him. I can't tolerate his current behavior and I feel that it is negatively affecting me.
