Answer: The apparent decrease in others' regard for us that results in hurt feelings is knwon as Relational devaluation
Step-by-step explanation:
Relational devaluation refers to an unpredicted decrease in how a partner considers the closeness and value of a relationship to be in one self. This means the relationships may disappear at any time or come to an end.
It brings hurt to know that someone doesn't feel the same about the relationship and to notice that they no longer regard it as valuable to them anymore which means they can walk out of it at any given time. It may create feeling of unworthy to the person who still considers the relationship to be worthy.
