Would You Leave in This Situation?

My (28F) partner (29M) decided to move out temporarily after an incident. While traveling together, an unexpected medical emergency occurred on public transport. I froze in shock and didn’t assist like others did. My partner, disappointed by my reaction, felt it revealed a lack of empathy. Was this situation a red flag, or a moment of natural human hesitation? Is it fair for one incident to define a relationship? #WhatWouldYouDo #RelationshipTalk #EmpathyInAction
