Identify a story that can be compared and contrasted with "The Story of an Hour?"

I wonder if "The Gift of the Magi" by O. Henry might be a
possibility.  In each of the stories, the reader is presented with a kind of snapshot of
a married couple and in each of the stories, there is a surprise ending that reveals to
the reader the state of the marriage.  As for differences, one marriage is so dreadful
that the idea of continuing it actually kills the wife, and in the other, the marriage
is revealed to be so strong that the husband and wife willingly give up their most
precious possessions for the other.

I do not know whether
your assignment permits you to go beyond the texts, to examine the era and or the
authors, and this is something that you might want to clarify with your teacher.  The
publication dates of the stories are only eight years apart, written in the same era,
but they are such completely different takes on marriage.  Something to think about is
whether or not a male of that era, O. Henry, in this instance, had a more positive view
of marriage than a female of the era, that female being, of course, Kate Chopin, who
wrote frequently on the struggles of women.
