It's bad as film analysis but it also doesn't really make sense factually.

>Four months have passed since the crash, and two years pass from the first date to their wedding date. Two years! Two years seems like an awfully short turnaround for a woman to be married when she’s not even sure if her fiancé is still alive or not.

A quick Google search tells me:

>By 25 months after the spouse's death 61% of men and 19% of women were either remarried or involved in a new romance.
>
>Younger age was a predictor of becoming involved in a new romance for women.

This is for all ages and younger people are more likely to be in a relationship so the actual odds of "this woman" (who it needs to be said, is a fictional creation) are at least higher than 20%.
