Grab some tissues.
Victoria and Jason
The best bit: Essentially the whole video. But especially 2:30 when Jason's mother gives a speech in memory of his grandmother.
Ryan and Amanda
The best bit: At 2:18 when he surprises her with not only a proposal, but everyone she loves and a wedding based on her Pinterest board.
Jonathan and Dwayne
The best bit: The beginning when Dwayne tells the story of how he proposed to Jonathan. Then at 3:15 when the two see each other for the first time on their wedding day and you can't help but cry with them.
Kelly and Dustin
The best bit: 4:14 when Dustin starts tearing up when he sees Kelly.
