Another pair of brave singles walk down the aisle, but will a frosty first impression leave one bride out in the cold? And will there be harmonious honeymoons for our freshest newly-weds?

Two more singles get wed, but could a bride's pursuit of perfection jeopardise her chances of finding love? Plus, more honeymoon hubbub as one groom threatens to ruin any chance of romance.

One more couple say 'I do', but will the groom's humour leave his wife unamused? And as the final honeymoons continue, is there trouble in paradise for one pair?

As the newlyweds return from their honeymoons, all nine couples move in together and adjust to life in their marital homes, ahead of the first dinner party.

The inaugural Commitment Ceremony sees all nine couples meet the experts for the first time. For some, it's an opportunity to showcase their success, but two couples clash.

It's Experts Week, and the newlyweds face their first set of challenges specifically designed to strengthen and develop their marriages. Charlene's intimacy workshop spices things up for some of the new couples, while one bride's patience wears thin with her new groom.

The second dinner party serves up romantic confessions for some, but one bride struggles to find the support and validation she's looking for from her husband, leaving her questioning her marriage.

At the commitment ceremony, some relationships blossom like their wedding bouquets. But for others, there's communication calamity and a 'do-I-stay?' dilemma.

It's the time some couples dread... in-laws week! But one couple's breakthrough proves that in-law intervention isn't always bad. Plus: a new wedding!

At another new wedding, a high-speed bride and laidback groom say 'I do'... what could go wrong?! And will more in-law intervention help or hinder harmony?

Instant sparks fly in a passionate ceremony as our final couple get wed. And as the in-laws keep coming, one bride falls short for a frustrated friend.

The final newlyweds embark on their honeymoons, and while one couple realise that physical intimacy doesn't always lead to a deeper connection, another pair are pushed to breaking point by one partner's constant need for reassurance. Also, a bride's family deliver stern words of warning to her badly behaved husband.

At the third dinner party, a new bride's arrival and honeymoon antics stir up emotional reactions in the group. Also, another bride is forced to come clean about the lack of spark in her relationship.

It's Commitment Ceremony time, and while the cracks start to show for one couple, another pair finally make some much-needed progress. The experts force another couple to seriously consider the future of their marriage.

The couples take some time apart as the group splits in two for separate days out. But the relaxation soon turns to drama when one groom confesses his true feelings about his bride, and the burden of a long-hidden secret causes an explosive clash for one pair.

It's the much-anticipated 'Love/Hate Week', as the experts push the couples to reveal their biggest likes and dislikes about each other. While some bonds grow stronger and feelings are shared, emotions boil over when one groom reaches breaking point after hearing his wife's critiques.

At another dinner party, some couples share their positive progress, but one bride is left desperate for answers about her marriage. Also, when one couple's authenticity is questioned, tensions explode.

The group face the experts at another emotionally charged Commitment Ceremony. One couple affirm their love, and a bride's behaviour is called out by the experts and the group.

It's rural retreat time, and a welcome romantic break for some. But rumours about a bride's behaviour spiral and lead to a confrontation, while another bride learns a heartbreaking truth.

An unexpected arrival at the countryside retreat leads to a devastating showdown. And as one marital breakdown continues to spiral, the group are caught in the crossfire at an explosive dinner party.

The group return from the retreat and head straight for the Commitment Ceremony. Some couples reap the rewards from their time away, but for others turmoil grows, departures loom, and one bride questions whether her marriage is beyond repair.

It's Partner Swap Week, where everyone spends time living with a different bride or groom. While absence makes one groom's heart grow especially fonder, time apart reveals troubling fault lines in other marriages, testing one couple's relationship.

In the aftermath of Partner Swap Week, the couples gather for their sixth dinner party. While one groom can't wait to share his romantic realisation, others have less cause to celebrate, and one couple's downward spiral continues.

It's time to play happy families as Homestays get underway, giving the couples a glimpse of what life could be like outside of the experiment, and the opportunity to gain insight from loved ones.

Homestays continue, as the remaining couples return to their hometowns and reunite with friends and family. An emotional mum voices her concerns about her daughter's future, and another bride recieves feedback from a friend.

At the final Commitment Ceremony, the remaining couples seek the experts advice one last time. As crucial decisions are made, one bride faces up to some difficult truths, and the revelation of a secret scandal shocks the group.

On their final dates, one couple face up to their long-distance future in a deeply emotional discussion, and for another, an ill-chosen date venue sparks a rollercoaster of emotions that leaves huge question marks hanging over their marriage.

It's the final boys' and girls' night out, with old friends joining the fun. But one familiar face's shocking revelation sparks the mother of all showdowns.

At the final dinner party, one couple question whether their love can survive on the outside and another clash over double standards. And it's vow renewal time!

As the couples return home to prepare for vow renewals, one couple leave the apartments on far from good terms and a bride questions her husband's feelings.

It's commitment crunch time as the vow renewals continue. One emotional groom questions whether he's enough and one couple decide if long-distance can survive.

It's the reunion dinner party and in true MAFS style, across-the-table action is served as two brides clash. One groom faces a reckoning for his behaviour as the couples learn which pairings survived in the outside world.

In the reunion commitment ceremony, the couples celebrate the journeys and confront their issues as they look to the future. One husband makes a final admission that shocks the whole group.
