"Often pride prevents consciousness of jealousy but the behavior is the same. This situation is at times made worse by the fact that the suspected mate beholds the helplessness of the jealous one with unconscious satisfaction and fails to find the words or the tone that would hold jealousy within bounds."
=Making People Jealous.= This is why the efforts made by certain men and women to arouse their sexual partner's jealousy are productive of rather baneful results. They do not bring out the love or affection of the person who is made jealous but his worst egotistical and sadistic traits.
One of the strongest factors in love being the egotistical satisfaction we derive from the possession of the love object and the realisation of our influence over it, our love wanes rapidly when we see another person wielding much power over it.
The stratagem has temporary effects which may deceive the person using them. The jealous lover, at first makes decided efforts to regain his position, but he soon feels swayed by egotistical considerations which lead him toward the line of least effort. Slighted by one woman, he turns to another for consolation, and usually finds it.
The man or woman who considers it shrewd to let his mate suspect that "there are others," for one thing encourages faithlessness by creating a precedent. It is especially when the other (or others) are distinctly inferior in appearance or position that this sort of game ends disastrously. The woman who likes to mention the attentions bestowed upon her by some inferior man and seems to enjoy them accomplishes two things. She makes herself appear inferior and "easy" and makes her lover feel that any inferior man could compete with him for her love and that, hence, he himself must be inferior.
He may run away from her to escape that feeling of inferiority.
If he does not leave her, he no longer feels compelled to make any effort to please her, since worthless homage seems so valuable to her.
=Jealousy is the Hell of Love= and no one should dare to open its gates lightheartedly.
One should be the more careful in arousing jealousy as the "green eyed goddess" now and then is responsible for some killing. The sexually jealous husband may kill his wife's lover, the egotistically jealous husband may kill the unfaithful wife. The former removes temptation from her path, the latter avenges his wounded egotism.
