Dyadic phase: There a a series of confrontations when they cannot avoid talking about the relationship further. Determination to continue breaking it or try repair it. "I would be justified in leaving".
Social phase: Involves couple's social networks and the break up is made public. Mutual friends find they have to pick a side. ie. close friends are told and gossip.
Grave dressing phase: Moving on and tidying up memories. "Time to get a new life".
