What conclusion does ophelia make about hamlet's actions in act 2

Scene 1: Act 2 begins with Polonius speaking to one of his servants, Reynaldo, about his son, Laertes, who has by this time returned to Paris. We see Polonius in the act of sending Reynaldo after Laertes to inquire into his son’s conduct. He instructs Reynaldo very precisely in the method of obtaining this information. First, Reynaldo is to find out from strangers in Paris about the prominent Danes in the city without revealing that he has any particular attachment to Laertes. When Laertes’ name comes up, Reynaldo is to pretend to have some distant knowledge of him, and is further to suggest that he knows of Laertes as something of a happy-go-lucky youth given to gambling, drinking, fencing, swearing, fighting, and whoring. By this path of insinuation, Polonius explains, Reynaldo will hear from his hypothetical Parisian interlocutor the unvarnished truth about Laertes’ conduct in France. Having thus prepared Reynaldo to spy on his son, Polonius sends him off. Ophelia enters, distraught. She tells her father that Hamlet has frightened her with his wild, unkempt appearance and deranged manners. After Ophelia describes Hamlet’s behavior, she further reveals that, as per Polonius’ orders, she has cut off all contact with Hamlet and has refused his letters. Polonius reasons, thus, that Hamlet’s madness is the result of Ophelia’s rejection. He had thought that Hamlet was only trifling with her, but it turns out (he now declares) that Hamlet was indeed deeply in love with Ophelia. Polonius hurries off to tell Claudius and Gertrude that he has discovered the reason for their son’s odd behavior.
