A quote I think fits Ophelia's view on Hamlet very well. Hamlet changes from what Ophelia believed to be a man who loved her into someone who has lost his mind who she must no longer love. He claims their relationship was a lie, and then tells Ophelia to "get thee to a nunnery" and "trust no man", letting her know she should stop believing in him, even if it hurts.
Whether you call yourself "Smart or Wise": The Word of God counsels us: "To be quick to hear, slow to speak, and slow to wrath( Get Even with others). Because man's wrath does not work out the Righteousness of God"( James 1:19-27)
