Past relationships can leave us with worries about future relationships. Relationships can leave deep wounds, even if they ended amicably. People can get hung up on whose 'fault' the end of the relationship was. Responsibility is usually at least partly shared in the end of a relationship. Acknowledging our part in both making and breaking the relationship can help us understand our strengths and weaknesses in relationships. Changes in circumstances or people can cause a relationship to end, even if both parties tried to save it. Fear of the same thing happening again can prevent people from starting new relationships, but it's not necessarily a reason to avoid them.
