It might seem that running away from a relationship where the other person has cheated is the coward’s choice, but those who know their partner will never be faithful could have the right idea. Their choice to leave is one that will eventually be recognized as correct, but they should take the time to calm down and asses their situation first. Leaving quickly can cause them to forget their own well-being, and they might be abandoning assets to the person who has hurt them.
Calmness is not always easy to claim in a situation like this, but it can be the best way to ensure a person who has been betrayed will be able to hold their head up once the situation is resolved. Remembering to take their possessions with them can be as important as taking their self-esteem when they open the door. It is their own life they should be concerned with, and they should ensure they leave nothing of their own for the person who has used them badly.
