Understanding each other comes easy, but it also shows your shortcomings.
This self-reflection may be difficult and demand patience and maturity.
Double Sensitivity: As two sensitive people, confrontations can become highly emotional and simple matters blown out of proportion.
Being conscious of this inclination can help you through difficult times.
Lack of Balance: Too much similarity might cause relational imbalance. Diversity and excitement are needed to keep the spark alive.
Personal progress may stagnate if both spouses have the same qualities and weaknesses. Encourage one other to try new things.
