Powerful story. The drama of so many couples wonderfully depicted here. It goes on to show that silence can in fact kill us.

His married life had fallen into a hole where they had not been able to get him out, like a broken-down car in the middle of nowhere with tired and weak passengers.

I think that many would identify with it. The sad or ironic thing is that in most relationships, like with most mechanical failures, it is just a matter of looking at the right place, checking the right part, doing the right thing. The skillful mechanic does not even need to get dirty. Most of us know nothing about cars, even though we drive them.
