How come Ophelia doesn't want to see hamlet anymore?

Ophelia distances herself from Hamlet primarily due to the emotional turmoil caused by his erratic behavior and the pressure from her father, Polonius, and brother, Laertes, who warn her against getting involved with him. After Hamlet's harsh rejection during their encounter in Act 3, Scene 1, Ophelia feels betrayed and confused, leading her to decide that it is best to avoid him. This decision reflects her struggle to navigate her loyalty to her family and her feelings for Hamlet amid the chaos of the royal court.
