And then what do you do? Stand there staring at his back a few seconds before walking away? Or do you challenge him? Do you say, "No, please don't turn away from me, I'm not finished talking about this," and not let him end the discussion that way? If it's important for you to talk about with him, you need to let him know. Do not accept his dismissal of you! Tell him how much it hurts that he doesn't want to share things with you and gives up on you so easily.
