They're now saying that the 21st century is going to be the century of what they call the "symmetrical marriage," or the "pure marriage," or the "companionate marriage."
Λένε ότι ο 21ος αιώνας πρόκειται να είναι ο αιώνας του ονομαζόμενου "συμμετρικού γάμου," ή του "καθαρού γάμου," ή του "συντροφικού γάμου."
