Bright, Your h could very well be angry at himself or something may have happened during his day before he was in contact w/you. They lash out at the person closest to them because they feel safe in doing so.
My advice, please stop taking his actions personally. I know it's difficult to do, but you have to remember you aren't to blame for how he feels right now or what is happening in his world. He's the only one that can take that blame on for now. You didn't do anything wrong and maybe, just maybe, he realizes it and is feeling angry w/himself for putting both of you in this situation...but time will tell. You didn't break him, therefore you can't fix him.
As long as your actions are kind, civil and courteous, then you have nothing to worry about on your side of the sandbox. Leave him to breaking his little shovel and putting holes in his sand pail.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
