Jealousy is a psychology that includes both rational and irrational parts.
Rational jealousy has a large scope and is even more harmful to society. Irrational jealousy, mainly jealousy of the individual. The main thing is the jealousy of love.
Shakespeare's Othello and Romeo and Juliet are vivid portrayals of this love and jealousy.
The jealous person himself has always attributed this jealous emotion to the other party. In fact, love jealousy is the emotional projection of the jealous person himself.
Causes include genetic inheritance, repressed childhood memories of individuals, and emotional personality formations.
It is manifested as uneasiness, anxiety, inferiority, irritability, blame, blame, reprimand, anger, anger, criticism, etc.
The excuse is often that I love you too much, I am afraid of losing you, I can't live without you, I can't do without you......... A series of nonsense. The more such a person is, the more he has no practical ability to guarantee a safe, intimate, intimate, and private environment for his lover.
So his or her jealousy persists.
