Is divorce genetic?

Adopted children have the marital traits of their biological parents.  We used to think that behaviors that led to divorce were handed down psychologically, but now we know that genetic factors better explain divorce.  One of those inherited personality traits is intense negativity, which I call the “Eeyore effect” where nothing is right, and everything is wrong all the time.  Another trait is the tendency to express very strong emotions regardless of the damage they cause.  Also contributing to divorce is the highly neurotic and anxious partner who’s hypercritical and sees every little flaw in their spouse.  Constant criticism leads to skirmishes and a lack of intimacy.  Does this sound like your marriage?  Consider going into therapy to explore your backgrounds to see if inherited personality traits are undermining your “happily ever after”.
