If you feel going dark is working, then do more of what's working. Try to act as if next time you speak to H (since you got a positive response), even if you're not good at it. If you keep doing it, it becomes more natural. If H is in the Depression stage, he may be there for a while - don't expect the next stage too soon and set yourself up for disappointment. They sometimes peek out of the tunnel but run right back in. It was a positive talk nonetheless.
