Good communication in relationships boils down to active listening, emotional awareness, and thoughtful expression. Key practices include using "I feel" statements, choosing the right timing for discussions, and validating your partner's feelings even during disagreements. Avoid criticism, defensiveness, and stonewalling. Instead, focus on understanding each other through daily check-ins, clear expression of needs, and taking responsibility during conflicts. Remember to take breaks when emotions run high and address one issue at a time. Success comes through consistent practice and mutual commitment to growth.
