In "The Jilting of Granny Weatherall," how is Granny Weatherall jilted for a second time?

Although Granny feels jilted by George, the fiance who left her at the alter some sixty years ealier, many believe the jilting that bothered her most was the jilting by God.  Near the age of 20, she was left alone at an alter with a priest. The man she loved never showed up.  After reliving that moment over in her mind many times, Granny is once again faced with lying in a bed alone with only a priest there with her.  She waits for a sign from God in the last lines, yet there is nothing.  She is left with nothing but the unfinished business that she was unable to share with her family in her last moments on earth.
