 Kind of a sad sound, isn't it? Hear the embarrassment, the reluctance, the pulling away? If you recognize it, then you know exactly what to do. Listen. It might take a long time. A drive together or a walk that turns into a talk, and that turns into an arm around his shoulder that means you understand. That's when you can really talk, when he knows you understand. Then the both of you can figure out how not to make the same mistake again. I know it's tough. Keep at it. You're doing great.
