What does the representation of the forest indicate according to lines 163-175? In wife's tales

163-The wife asks if it is customary in King Arthur's household for a husband to be so standoffish towards his wife.

165-She reminds the knight that she is his love and wife, and the one who saved his life.

170-She says that she has never done wrong by the knight. Why, then, is he treating her this way on their wedding night?

172-The hag says her husband is acting like a crazy man. What is her guilt? She demands that her husband tell her what she has done wrong, promising to correct it if she is able.

174-The knight replies that the hag will never be able to fix the problem, which is that his wife is so ugly, old, and low-born that it's no surprise he tosses and turns.

175-He wishes God would break his heart within his breast.
