What does Hester resolve to do and why? In Chapter 13.

Hester resolves to help Dimmesdale by rescuing him from Roger Chillingworth. She has grown strong enough as a woman to see that her previous pact with Chillingworth, in which she promised not to reveal who he really is, was the wrong decision. She therefore decides to meet him, and soon thereafter she finds him in the woods collecting medicinal herbs.
