TIL that the happiest marriages are those where the wife is able to calm down quickly after arguments.(r/todayilearned)
There’s a whole book written on relationship fighting dynamics, called Seven Principles for Making Marriages Work by Dr. John Gottman. His research is very similar to the study in OP’s article; he basically watches couples argue and follows their relationships for a few years afterwards. He defined several argumentative styles that are toxic, and several ones that are healthy.
What he found is that couples who are enamored of each other are likely to have healthier arguments (less contempt, less nasty put-downs and character insults), and are more likely to work on the deeper root issues than others. As a result, they have healthier relationships. Couples who don’t figure out what the real issue is end up with a nasty bout of character insults and usually end up in a failed relationship.
EDIT: Thank you so much for the gold!
