It's a useful technique, one I use often with my Ds and H.
"You seem angry/ tense/ withdrawn.... is everything OK?" "You seem really happy/ relaxed. Did your weekend help you?"
"You seem upset by (this situation); what upset you about this?" "that must be hard for you"
But I don't tell him what to do, I allow him not to answer, and I leave silence gaps in the conversation that he can fill with more information if he wants.
