The way I see it, the best shot Kris has at waking her hubby up from his dark cloud is changing her own attitude about herself and him, getting a bounce in her step and a zest for life, being kind and gracious, assertive, honest and as unemotional as she can muster under relational stress with him....and playful.
If that doesn't wake him up to get on board....well....I don't know what to say.
