Jealousy in men's and women's feelings refers to the feeling of being as sour as vinegar when seeing the person you like contact or communicate with other opposite sex; That means I like her and care about her. Both men and women are selfish and exclusive. I don't want the opposite sex I like to be hypocritical to other opposite sexes. When I can't stop her from laughing or dating other members of the opposite sex, I will feel sour inexplicably, have an emotional crisis and be afraid of losing the game.
