During the latest Married at First Sight: Unfiltered broadcast hosted by Season 1 MAFS participant Jamie Otis, Dave watched back a clip of Amber telling him during a dinner out that he tended to be critical and judgmental of her.
"You know, through most of the season, I probably could have chosen my words better," Dave admitted. "And that's something I'm realizing and taking forward with me."
Dave added, "There is a difference between us, but I really didn't mean it in a bad way."
Dave and Amber chose to stay married on "Decision Day" after overcoming many obstacles in their relationship over the course of the eight-week experiment.
Not only did Amber face insecurities about her physical appearance and overall performance as a wife, but Dave struggled to express himself emotionally and give Amber the reassurance she needed to feel confident in their connection.
When Jamie asked Dave whether his conversation with Amber at dinner that night gave him any concerns going into "Decision Day," Dave replied, "Sure. Yeah."
"I think there was concern going into 'Decision Day' certainly. It wasn't an easy eight weeks," Dave confessed.
