Demeter's feelings towards Zeus and Hera are complex and not explicitly characterized by jealousy in myths. While she does experience anger and hurt due to Zeus's actions, particularly regarding the abduction of her daughter Persephone by Hades, her emotions are more focused on maternal grief and the desire to protect her daughter than on jealousy towards the couple. Demeter's relationships and feelings are primarily driven by her role as a mother and goddess of agriculture, rather than romantic rivalry.
