The concept didn't work out for at least one couple -- Monet and Vaughn -- but the show was a major hit for A&E's fyi network, as the season finale was the most-watched telecast in the network's history.
The strategy also seems to be working for Jamie and Doug who have managed to keep their marriage together.
"I have a lot of issues," said Jamie. "And I'm kind of a tough one to love, because I'm so guarded and I make it difficult for someone to be able to love me, because I guess I'm so scared of it. [Doug] never says anything negative, and [he] always has my back."
"It wasn't how I imagined a fairytale would go," Doug told Jamie. "But I knew you were worth it."
