Yes..you have repented of causing him to lose his job.
But...for a man, his identity is his job, his vocation. SO physchologically, you've emasculated him. He feels like your bitch right now. And until he gets his footing back in the work force, he'll always feel like he's half a man. How can he forget you cost him his job when he's unemployed?
Add that to guilt, public shaming and depression.
He must be a joy to live with.
Perhaps he needs encouragement. Not nagging. Tell him you are encouraged by his job seeking efforts and that it means a lot to you. Maybe let him know you care about him a lot (avoid the word love) and that you think he could really benefit seeing someone (a therapist) for himself to help him through this slump. Encourage him to do something for himself, to care for himself, because he's really worth it.
You know, it feels like he's only one good belly laugh away from starting to see hope in this situation.
I think he's lost hope and he's just going through the motions right now.
