Couples are formed, and the news is shared with the world on Facebook by changing statuses from “Single” to “In a relationship”.
Relationships start with a period of courtship: on Facebook, messages are exchanged, profiles are visited, posts are shared on each other’s timelines. The following graph shows the average number of timeline posts exchanged between two people who are about to become a couple.
During the 100 days before the relationship starts, we observe a slow but steady increase in the number of timeline posts shared between the future couple. When the relationship starts (“day 0”), posts begin to decrease. Presumably, couples decide to spend more time together, courtship is off, and online interactions give way to more interactions in the physical world.
