If a woman is not supported in being unhappy sometimes then she can never truly be happy. To be genuinely happy requires dipping down into the well to release, heal, and purify the emotions. This is a natural and healthy process.
If we are not feel the positive feeling of love, happiness, trust, and gratitude, we periodically also have to feel anger, sadness, fear, and sorrow. When a woman goes down into her well is when she can heal these negative emotions.
Men also need to process their negative feelings so that they can then experience their positive feelings. When a man goes into his cave is a time when he silently feels and processes his negative feelings.
When a woman is on the upswings she can be fulfilled with what she has. But on the downswings she then will become aware of what she is missing. When she is feelings good she is capable of seeing and responding to the good things in her life. But when she is crashing, her loving vision becomes cloudy, and she react more to what is missing in her life.
Just as a glass of water can be as viewed as half full or half empty, when a woman is on her way up she sees the fullness of her life. On the way down she sees the emptiness. Whatever emptiness she overlooks on the way ups comes more into focus when she is on her way down into he well.
Without learning about how woman are like waves men cannot understand or support their wives. They are confused when things get a lot better on the outside but worse in the relationship. By remembering this difference a man holds the key to giving his partner the love she deserves when she needs it the most.
