Was Madame Forestier angry when Matilde blamed her for her misfortune?

In “The Necklace” by Guy de Maupassant, Madame Forestier seems more astonished than angry at Madame Loisel's revelation.
 Many years after the incident with the necklace, the women meet each other as they walk along the Champs-Elysees. Madame Forestier does not recognize her friend who has changed immensely due to her years of poverty and manual labor. Madame Loisel decides to tell her former friend the true story of the necklace. At this point, Madame Forestier seems taken back by what she hears and attempts to walk away. When she realizes the truth, she stops and shows Madame Loisel empathy for the misunderstanding.

Madame Forestier, deeply moved, took her two hands. "Oh, my poor Mathilde! But mine was imitation. It was worth at the very most five hundred francs! . . . "
