"This is a milestone that I don't take lightly," Doug, a 36-year-old software salesman, told the New York Post.
Doug and Jamie have the longest-running marriage stem from the franchise, although there are only three other successful couples who starred on Seasons 1 through 7. (Season 8 is currently airing on Lifetime and viewers have yet to see "Decision Day.")
"This is the longest relationship that I've been in in my life," said Doug, who currently lives with Jamie in Monmouth County, NJ.
While Doug insists Married at First Sight "can create a fairy tale," according to the Post, his relationship with Jamie started off extremely rocky.
In fact, after watching the couple's wedding, the majority of fans believed Jamie and Doug wouldn't last.
"I had a panic attack," Jamie, 32, recalled of her experience marrying Doug.
The couple said Doug was "sweating" and "twitching" at the altar, and when he saw Jamie for the first time, he was ecstatic.
"I couldn't have been happier, seeing someone that was just absolutely gorgeous," Doug said.
