One couple, however, opted to get a divorce on Decision Day, and those individuals were Molly Duff, a 25-year-old commercial insurance adjuster, and Jonathan Francetic, a 28-year-old U.S. Army veteran and financial associate.
During the reunion special, fans watched Shawniece reveal the big news of her pregnancy with Jephte, and Molly and Jonathan also dished on the demise of their relationship that initially started out strong on the show.
And Ryan and Jaclyn proved they are still enjoying their life together and have learned so much about love, communication and commitment through appearing on the show.
"Seeing you walk down the aisle, it was the best day of my life," Ryan gushed.
Molly and Jonathan then shared how it was probably a surprise to viewers their marriage ended in divorce because they are so similar and were matched for all the right reasons. Not only did they share the same values and goals, but they also have a desire for adventure, travel and fun.
"I think the way we started communicating was off... it was a bumpy road to recover and we just never did," Jonathan explained.
Molly admitted it was "a shame" she wasn't attracted to her husband, and during the reunion special, she and Jonathan finally removed their wedding bands they had been wearing to avoid questions from colleagues and acquaintances as well as awkward discussions.
The Married at First Sight experts -- Dr. Jessica Griffin, Dr. Pepper Schwartz, and Pastor Calvin Roberson -- agreed Molly and Jon were "the most confusing couple" on the show because they seemed to get along great and there was an obvious initial attraction that was mutual between the two spouses on their wedding day.
Molly said her attraction to Jon simply declined over time, and she couldn't quite put her finger on why.
"I don't feel like he did anything wrong, but I didn't sabotage it," Molly insisted, adding that she realized she was not sexually attracted to Jon when he was acting "hyper" and "boyish" on their honeymoon.
"I gave it my best shot. Had Jon said he wanted to keep trying, it would've been hard for me to not keep trying," Molly confessed.
Pastor Calvin then pointed out, "It sounds like this marriage could have been saved but you were both trying to protect yourselves."
Molly asked Jon flat out, however, whether he would have stayed married if she said she wanted to keep trying on Decision Day, and Jon said his mind was already made up and things were over between them.
"Do I want to be in an abusive relationship? The reality of it is no," Jon noted.
Afterward, Shawniece and Jephte discussed how they love people differently. Jephte was terrified of getting hurt, but Shawniece is fearless when it comes to giving her love to another.
Shawniece told Jephte they need to continue to make marriage about them -- not about other people and their wants and needs. She also gushed about how Jephte saves her from getting too caught up in the stress of life at times. In turn, Jephte called his wife "sweet and caring," saying she's a good person.
"My heart is opening up for you... I'm trying to make room for you and we're getting there. We're getting there together," Jephte told Shawniece.
As for Ryan and Jaclyn, Jaclyn said she actually loved how Ryan was childlike, fun and easygoing. Ryan said his marriage was "like a fairy tale," and he explained how Jaclyn is a great person, not to mention beautiful. Their two families also apparently clicked right away.
"I think you're a good guy and you're funny and sweet and you have a lot of charisma and can be charming," Jaclyn told her husband in reply. "That's an extremely attractive quality."
Jaclyn shared how she learned not to walk away from something during challenges or difficult times, and Ryan acknowledged that a marriage is a working relationship and a couple must overcome a lot together.
However, one thing was clear -- Ryan and Jaclyn are both passionate people, and they are passionate about each other both physically and emotionally.
A female friend of Jon's then stepped onstage to talk about what went wrong between Molly and Jon. Jon's friend confessed his decision to film an argument was aggressive and uncharacteristic, but she noted Jon must have been "pushed" to get to that point.
Jon's pal also revealed he had dealt with a controlling ex-girlfriend and it took him a very long time to even become angry with her.
Jon then insisted his decision to make the video was not an attempt to set Molly up. Jon explained that Molly always accused him of twisting her words, so he made sure through this video her words would not be twisted.
Molly also argued that Jon was the one who started their fight in Orlando, FL, at the bar by "yelling" at her.
Getting back to Jephte and Shawniece's romance, the pair decided to prove their commitment to one another by getting matching tattoos of the number 8. The number represented Married at First Sight's eight-week experiment and how they wed during the eighth month of the year.
Eight was also Jephte's football number in school, and Shawniece was born in 1988. In addition, Shawniece pointed out that if you turn the 8 on its side, it becomes an infinity symbol, representing how they want their relationship to last forever and beyond.
"This was an amazing experience and we will forever be a part of each other's lives," Jephte said during the reunion.
Footage then flashed to two months after filming the reunion special, with Shawniece gifting Jephte a package to open. Jephte soon discovered his wife had given him baby sneakers, and Shawniece referenced his desire to take "baby steps" in their marriage since the start of the process.
Shawniece began to cry, confessing she was both "nervous and scared" about the baby since they were still trying to figure out their marriage. Both individuals, however, agreed they were going to be great parents.
Although Jephte appeared surprised and a little taken aback, he promised Jephte he would always be there for her, and they sealed the emotional conversation with a sweet embrace.
"When I found out I was pregnant, I was absolutely shocked. I was in the emergency room because I felt awful and had no idea what was wrong. They came back and told me all my symptoms were from pregnancy and that I was pregnant," Shawniece told People at the time.
"[But] I've always wanted to be a mom. I've always felt like that's my purpose in life -- to recreate some little Shawnieces in life. I think it's the greatest gift a woman can have. Life is a beautiful thing!"
