We've past the halfway mark and it's time for the annual Couples Retreat. Our happy couples are loving the change in scenery, until one bad joke sends the retreat into meltdown.

As the retreat continues, actions from the Girls and Boys nights leave one couple isolated from the group. Then, at the final drinks night, lingering tensions reach boiling point.

It's the day after an explosive couples retreat, and following the intense week away - our newlyweds are now attending the fifth dinner party of the experiment.

Tensions boil over on the couch during the fifth commitment ceremony of the season.

As we approach the halfway point of the experiment, couples attend the fourth dinner party; one marriage implodes in a shocking tirade that will leave everyone speechless.

Family and friends week begins and the couples gain perspective from their partners' loved ones; the newlyweds enter the apartments for a crash course in married life.
