It sort of restores my faith in these romances.:boggle:
I believe that Mary and Byron are the only Bachelor couple who didn't break up. (although it looks like Charlie and Sarah may be back together)

On the Bachelorette side, only Trista and Ryan have survived.

That makes a total of 16 seasons of these two shows, and only one marriage.
I suspect internet dating might be a safer place to put your "romance faith"!
