And I’ll still recommend GK Chesterton’s “The Superstition of Divorce”, not as Orthodox spiritual reading but as an explanation in secular terms as to why the teachings of the Church are right and the ideas of the modern world (which so many of us hold) are wrong.

A teaser excerpt from chapter 1:
“...
Such people say they want divorce, without asking themselves whether they want marriage. Even in order to be divorced it has generally been found necessary to go through the preliminary formality of being married; and unless the nature of this initial act be considered, we might as well be discussing haircutting for the bald or spectacles for the blind. To be divorced is to be in the literal sense unmarried; and there is no sense in a thing being undone when we do not know if it is done.
There is perhaps no worse advice, nine times out of ten, than the advice to do the work that's nearest. It is especially bad when it means, as it generally does, removing the obstacle that's nearest.
It means that men are not to behave like men but like mice;
who nibble at the thing that's nearest. The man, like the mouse,
undermines what he cannot understand. Because he himself bumps
into a thing, he calls it the nearest obstacle; though the obstacle
may happen to be the pillar that holds up the whole roof over
his head. He industriously removes the obstacle; and in return,
the obstacle removes him, and much more valuable things than he.
This opportunism is perhaps the most unpractical thing in this highly
unpractical world. People talk vaguely against destructive criticism;
but what is the matter with this criticism is not that it destroys,
but that it does not criticise. It is destruction without design.
It is taking a complex machine to pieces bit by bit, in any order,
without even knowing what the machine is for. And if a man deals
with a deadly dynamic machine on the principle of touching the knob
that's nearest, he will find out the defects of that cheery philosophy.
Now leaving many sincere and serious critics of modern marriage
on one side for the moment, great masses of modern men and women, who write and talk about marriage, are thus nibbling blindly at it like an army of mice.”
