Screen for institutional commitment and virtue before marriage
Wilcox explains that people who have a 'symmetrical commitment both to one another and to marriage as institution' are far less likely to get into the dark places listeners worry about. He contrasts this with the 'soulmate' model that Liz Gilbert embodies, where feelings are paramount and divorce is just a way to find the next soulmate. He urges listeners to be discerning about character and shared values before marriage, so they are less likely to face the fundamental incompatibilities that produce misery.
Social and psychological: individuals who value marriage as an institution view obstacles as problems to solve rather than signs to exit. Shared virtues create a reservoir of goodwill and cooperation.
you want to try to find someone who shares your commitments to marriage to love who is also kind of… has those virtues that make for a good marriage, loyalty, charity, patience, fortitude.
