Psychologist Elisabeth Kubler-Ross identified five stages that a person goes through in dealing with a death (and there is the suggestion that this is not just a response to a physical process but also to a mental process and as such the ending of a relationship). We can identify these stages with the concept of Five Phase Theory, a concept stemming from Ancient China and dealing with dynamics of relationships..
I have listed Kubler-Ross' stages and mapped them to Plutchik's list of basic emotions and the Five Phase relationships [] and the associated trigrams of the I Ching as well as the generic IDM categories.
DENIAL - the 'death' did not happen.
Rejection - WATER [Water] (BOUND)
BARGAIN - Lets find a way to solve this problem, restore the past.
ANGER - anger.
DESPAIR/DEPRESSION - sadness etc.
ACCEPTANCE - incorporate the event into one's world image and move on.
Acceptance - FIRE [Fire] (BOUND)
