Here's a breakdown of his reaction:
* Anger and Frustration: Hamlet is furious at Polonius's interference. He sees it as a betrayal, especially since he genuinely loved Ophelia. He expresses his anger through bitter words, accusing Polonius of being manipulative and accusing him of being in love with Ophelia himself ("Get thee to a nunnery. Why wouldst thou be a breeder of sinners?"). He also expresses frustration with his own situation, feeling trapped and manipulated.
* Confusion: Hamlet's love for Ophelia is genuine, but he is also deeply disturbed by his father's death and his mission for revenge. This makes him unsure of himself and his feelings, leading to a confused reaction. He questions Ophelia's loyalty and wonders if she is truly in love with him or merely playing a role.
* Manipulation: While Hamlet seems genuinely upset, he also uses the situation to manipulate Ophelia. He tells her to "go to a nunnery," knowing that this would deeply affect her. This reveals a darker side to his personality, suggesting he might be using her to further his own goals.
* Self-Deception: His anger towards Polonius could also be a way for him to mask his own insecurities and fears about his feelings for Ophelia. He is afraid of being hurt, and by blaming Polonius, he avoids taking responsibility for his own emotions.
Ultimately, Hamlet's reaction to Polonius's command is complex and nuanced. It reflects his inner turmoil, his genuine love for Ophelia, his anger at being manipulated, and his willingness to manipulate others to achieve his own goals.
