Men are from Mars, Women are from Venus

Men Are Like Rubber Bands
Men are like rubber bands. When they pull away, they can stretch only so far before they come springing back. A rubber band is the perfect metaphor to understand the male intimacy cycle. This cycle involves getting close, pulling away, and then getting close again.
Most women are surprised to realize that even when a man loves a woman, periodically he needs to pull away before he can get closer. Men instinctively feel this urge to pull away. It is not a decision or choice. It just happens. It is neither his fault nor her fault. It is a natural cycle.
Women misinterpret a man's pulling away because generally a woman pulls away for different reasons. She pulls back when she doesn't trust him to understand her feelings, when she has been hurt and is afraid of being hurt again, or when he has done something wrong and disappointed her.
Certainly a man may pull away for the same reasons, but he will also pull away even if she has done nothing wrong. He may love and trust her; and then suddenly he begins to pull away. Like a stretched rubber band, he will distance himself and then come back all on his own.
A man pulls away to fulfill his need for independence or autonomy. When he has fully stretched away, then instantly he will come springing back. When he has fully separated, then suddenly he will feel his need for love and intimacy again. Automatically he will he more motivated to give his love and receive the love he needs. When a man springs back, he picks up the relationship at whatever degree of intimacy it was when he stretched away. He doesn't feel any need for a period of getting reacquainted again.

Women Are Like Waves
A woman is like a wave. When she feels loved her self-esteem rises and falls in a wave motion. When she is feeling really good, she will reach a peak, but then suddenly her mood may change and her wave crashes down. This crash is temporary. After she reaches bottom suddenly her mood will shift and she will again feel good about herself. Automatically her wave begins to rise back up.
When a woman's wave rises she feels she has an abundance of love to give, but when it falls she feels her inner emptiness and needs to be filled up with love. This time of bottoming out is a time for emotional housecleaning.
If she has suppressed any negative feelings or denied herself in order to be more loving on the upswing of her wave, then on the downswing she begins to experience these negative feelings and unfulfilled needs. During this down time she especially needs to talk about problems and be heard and understood.
My wife, Bonnie, says this experience of "going down" is like going down into a dark well. When a women goes into her "well" she is consciously sinking into her unconscious self, into darkness and diffused feeling. She may suddenly experience a host of unexplained emotions and vague feelings. She may feel hopeless, thinking she is all alone or unsupported. But soon after she reaches the bottom, if she feels loved and supported, she will automatically start to feel better. As suddenly as she may have crashed, she will automatically rise up and again radiate love in her relationships.
A woman's ability to give and receive love in her relationships is generally a reflection of how she is feeling about herself. When she is not feeling as good about herself, she is unable to be as accepting and appreciative of her partner. At her down times, she tends to be overwhelmed or more emotionally reactive. When her wave hits bottom she is more vulnerable and needs more love. It is crucial that her partner understand what she needs at these times, otherwise he may make unreasonable demands.
