I still think he is keeping something to himself though, which isn't fair. My husband married a 24 year old built-like-a-brickhouse woman. (Me.) He is now married to a 60 year old frumpy woman. I married a 33 year old drop-dead-gorgeous guy. He is now a 69 year old drop-dead gorgeous guy... until I look hard and see what others see him looking like. NOPE! He's still drop-dead gorgeous to me. (He has these steel-blue eyes that still twinkle when he's amused.) Attractiveness is choice, not measurements.
AND, I still think your soon-to-be-gone husband is a wuss. (Nothing personal to the husband that you still love. Let's just say that's specifically to the wuss part of him.) I suspect it has more to do with him feeling like he is less of a man, blahblahblah... all that stuff guys think that women never even get what they're thinking. (You know the stuff: "Men provide." "Bigger is better." "I'll fix it" when it can't be fixed and we can learn to accept that. )
I do hurt for you.
