In "The Necklace" if Mme. Loisel didn't lose the necklace what would happen?

If Mathilde Loisel did not lose the necklace nothing would have changed
for her.  She would have gone on being poor and miserable, longing for
more.

Mathilde feels like she should be rich, even though she
was born into a poor family and married a poor man.

She
had no gowns, no jewels, nothing. And she loved nothing but that. She felt made for that. She
would have liked so much to please, to be envied, to be charming, to be sought after. (p.
1)

Mathilde thinks of nothing...
