There are people who would actually question that logic.
Like a marriage is anything else but a ceremonial monogamy.
And hypothetically, if it were true, the same would apply to women. So cucks have logic, at least, one-sided cheats don’t.
They admit loyalty is valuable when they want to take it from the other party without giving it.
Update: I knew I’d read about this in Western canon.
“You call yourself a man,
For all you used to swear,
An’ leave me, as you can,
My certain shame to bear?
I ‘ear! You do not care —
You done the worst you know.
I ‘ate you, grinnin’ there. . . .
Ah, Gawd, I love you so!
Nice while it lasted, an’ now it is over —
Tear out your ‘eart an’ good-bye to your lover!
What’s the use o’ grievin’, when the mother that bore you
(Mary, pity women!) knew it all before you?
It aren’t no false alarm,
The finish to your fun;
You — you ‘ave brung the ‘arm,
An’ I’m the ruined one;”
Kipling nailed the sniveling cowardly type of man perfectly.
