The characteristic jealousy and envy of woman is a result of her limited ego. That is, with its delicate skin, which contains security, but is so easily punctured. The female ego is simple, with few dependencies, so when one of these dependencies does fail she is plunged into dire trouble. When her armour collapses, it collapses totally. The many safety supports that men have at their disposal are not her's. Nor does she have man's experience at carrying a burden of pain. Therefore she is expert at coping with things that fall within her sphere of submission, but she fails spectacularly when forced "outside".
