Unconditional love

Humans, whatever may be the case, cannot give each other unconditional love. We get upset or impatient when someone fails to make us happy. Furthermore, we base our love for someone on how well they perform. The root of this problem is sin, which causes constant mistakes, conflicts, and disappointments. No one is accepting, patient, and forgiving all of the time.
Therefore, human love is like chocolate because the pleasure doesn't last. None of us have the ability to accept people unconditionally. The affection we give to each other may taste good initially, but the thrill disappears as our selfish motives demand performance. And this problem lasts from the cradle to the grave.
I don't mean to sound fatalistic, but we must acknowledge the reality that human love is performance-based. It always has been and always will be. You can date anyone in this world, but that person cannot give your heart the unconditional acceptance that it craves.
This truth also applies in marriage.

Someone once asked a pastor, "What is your wife's opinion of you?"

He replied, "It depends on what day you ask her. Some days she loves me. Other days, I drive her crazy, and she wonders why she married me. My wife and I wish we could love each other perfectly, but it is impossible since we both sin and make choices that hurt each other. God is the only Person who loves us regardless of how we act."

Such is life: our take on it may differ but mankind suffers the ordeal of the communication fatalties.
