Try this one with him, set in front of him, you in a chair and him in a chair facing each other. Let him know that you will set there looking at eachother for as long as it takes until he tells you exactly what is bothering him. DO NOT CRITISIZE any thing he may say. Just ask this question over and over in a calm voice until he is ready to tell you what is bugging him, "I want to help you and I will listen, what is really bugging you?" I am a foster parent and this helps on some kids, it may take 1/2 hour to really get him to trust you are willing to listen to him but once he opens up to the truth (if he will) both of you will get along better and have a better grasp on how each other feels.
Good luck with him, he is at an age where he wants to become his own person!!
