The researchers also found that “greater hippocampal and amygdala activation was associated with being the person who did not initiate the breakup, feeling betrayed, or still holding positive thoughts about the ex-relationship.” Factors like attachment style, childhood neglect, and sexual orientation also influenced neural responses.

The authors note the need for more research but make a compelling case for recognising that, for some, heartbreak is more than just emotional; it’s biologically impactful too.
