Discord between my nephew and me, advice needed!

Thanks for all the kind words and encouragement everyone. He's my one and only nephew so I really want to make it work, but each day it seems worst...Just right now he was running in the hallways and as soon as I came out he ran back to his room and closed the door .

The root of the problem seems to be in his mind, at least, maybe something he thinks that you did.
Do your damnedest to understand what of your last actions toward him may have set him off.
In the process, study up on his affliction to see if aspects of it can relate to his sudden change in attitude.

Proceed carefully, this situation could turn into a serious problem for you.
