Truth & honesty are a must trait to keep bitterness & mistrust at bay in a relationship. Confronting partner calmly duly maintaining composure while discussing an incident affecting communication & creating rift in trust facilitates him/her express own views & perspective without loosing cool and getting into defensive mood leading to arguments. Positive interaction without looking for validation rather than being judgmental & acute loneliness motivates a person to repair what is lacking. Ego does not take a person anywhere it only destroys the sense of gratitude & happiness.
