Questions about Marriage & Long-Term
What is the most common cause of divorce?
Surveys consistently point to gradual erosion — lack of commitment, persistent unresolved conflict, and growing apart — rather than single dramatic events. Infidelity appears frequently but often as a symptom of a relationship that had already disengaged.
Is the honeymoon phase supposed to end?
Yes. The neurochemistry of early infatuation is not sustainable and typically settles between one and two years. The transition to companionate love is not a failure; couples who expect it navigate it far better than couples who read it as lost love.
When should couples go to therapy?
Earlier than most do. The commonly cited figure is that couples wait around six years after problems surface. Counselling is most effective before contempt has set in, and treating it as maintenance rather than a last resort substantially improves outcomes.
