G, I know that it is so hard for someone who doesnt suffer from depression to understand what it feels like. But believe me when I tell you that your h is just trying to get through the day. He really has absolutely nothing left for anyone else. This on top of a midlife crisis is an awful lot for someone like him.
Please try not to take it personally. And really it is best if you leave him be for now. He needs no pressure and any contact right now is extremely difficult for him.
