After eight weeks of marriage to a complete stranger, "Decision Day" has arrived and the time has come for Season 6's three couples -- Jaclyn Schwartzberg and Ryan Buckley, Shawniece Jackson and Jephte Pierre, and Molly Duff and Jonathan Francetic -- to decide whether they want to remain married or divorce.

However, for Jonathan and Molly, the decision already seems to all but official as Married at First Sight's recent episodes have already shown the couple living apart and saying they plan to divorce.

"It's 150 percent permanent," Molly told Shawniece and Jaclyn of her pending divorce on last week's Married at First Sight episode.  "Like not a single question [in my head]... there's no going back."

"We both know we're walking into Decision Day saying no," Jonathan told Ryan and Jephte during a separate discussion with his fellow male Married at First Sight co-stars.

Check out the below exclusive Reality TV World preview clip in which Jonathan sits down with his mother and talks about not being able to save his marriage to Molly.
