I like Floyd's suggestions. If he doesn't want to talk about work and work is stressing him out ... take his mind off of it and onto something else ... something better that involves you.
Also, I think your H also is beginning to realized how different he feels when spending more time with family than at work and that he feels better about the time he is with family vs the "satisfaction" derived from his job now, so family is becoming more important to him. Its someting that words from others just don't bear any weight ... its something that seems to have to be learned for oneself ... and most often its learned the hard way (speaking for myself anyway) .
