Why is the story called ''Happy Endings''?

Margaret Atwood's story "Happy Endings" is titled as such
to make an ironic statement on the nature of conventional marriage.  In the story, John
and Mary get married, and after the initial introduction, there are several choices of
how their marriage may have turned out based on cause-and-effect situations.  Some of
the endings are stereotypically "happy" yet the characters do not seem particularly
happy, while others end up a bit more disastrous.  Atwood uses the nonstandard structure
of the story to make a statement about the nature of relationships.  No one knows what
time and fate are going to bring, and the strength of a couple lies in their ability to
manage whatever might come their way.  Starting off by simply looking for a "happy
ending" trivializes the marriage, and is destined to lead to a most "unhappy"
ending.
