But Katina and Olajuwon, both 29, both took to Instagram this past weekend and shared photos from a recent vacation to Tulum, Mexico.
"Having life my way," Katina captioned a photo of herself on Friday.
Katina posted a photo with Olajuwon shortly afterward and wrote, "If we take off now we can catch the sun."
The pair was smiling big and looking cozy during their stay at Hilton Tulum Riviera Maya Resort, with Katina resting her leg on her husband's leg.
Olajuwon then uploaded a slideshow of photos of the couple on Saturday, including an image of the spouses smiling together on a boat and another picture of Katina resting her head on Olajuwon's shoulder while they flew on a plane.
"Never forget [you're] a fearless women! You fight every fear from animal's 'Alpacas' to deep ocean swimming 'snorkeling' and more!" Olajuwon captioned his post.
"Thank you for always having faith in whatever my heart and mind desires in life. Thank you for making sure I have a strong relationship with god. I appreciate everything you have taught me about myself without you even knowing it."
Olajuwon then gave a shoutout to Married at First Sight for having matched him with Katina, who was a total stranger to him when the experiment began.
"I also want to thank MAFS that I met @__slimmgoodie no matter what life brings to us! God is good in so many ways I get emotional just thinking of my life and how much I have matured as a man," he concluded. "I am truly thankful words can't express it! DICKERSON'S OUT."

When Olajuwon and Katina announced their split via Instagram last month, they wrote in a joint statement, "After one year of marriage and careful thought and consideration, we have decided to part ways."
They added, "However, this was not an easy decision to make. We leave our marriage with enormous love and respect for each other. We only ask that, at this time, our privacy is respected."
Based on the couple's recent social-media activity, it appears Katina and Olajuwon maybe split in late September or October, unless they put up appearances for their fans for longer.
On September 14, Olajuwon posted a music video featuring the couple embracing and having a date night to a song titled "Get You Home" by Chris Echols.
"People search their whole lives for this love you give me," Olajuwon wrote at the time. "I truly appreciate God's daily blessing which he allows you to give me everyday! Dreams to Reality."
And the pair also gushed about their one-year anniversary in an August 1 posting on Instagram.
Olajuwon uploaded a series of pictures from a photo shoot with Katina set to "Why I Love You" by MAJOR. He tagged his wife in the post.
"Love is not about many days, months, or years you been together. Love is about how much you love each other every single day," Olajuwon wrote. "Happy Anniversary, 7/23/21."
The stranger spouses had an immediate attraction and learned each other's wants and needs, but Katina had to step it up in the cooking and cleaning department in order to reach her husband's high expectations of his ideal wife.
Olajuwon admitted not having a wife who cooks well would be a huge sacrifice for him because "Katina doesn't have that skill... She can't cook."
And Katina confessed, "I told the experts I didn't want a passive man, but I think I got more than I bargained for."
Despite a couple of bumps in the road, including a big fight over Katina having an old dating app on her phone, Olajuwon and Katina appeared to be falling in love and in a great place heading into Decision Day.
During the April 20 episode of Married at First Sight: Afterparty, Olajuwon said that if he and Katina got a divorce, it would be out of "care for Katina's own personal goals in life."
She wanted to continue nursing school, and Olajuwon wasn't sure if she'd be ready to study, travel and have kids all at the same time.
But Katina determined on Decision Day their different timelines were not a dealbreaker for her, adding, "I want to stay married to you because I feel like our marriage needs more time than just the eight weeks."
In turn, Olajuwon said he loved the chemistry he had with his wife, and he gushed, "I love who you are as a person, I love to be around you, and your effort is what made me overlook all those things... There's no way I could ignore your effort."
Olajuwon therefore opted to remain married as well, saying he had a lot of respect for Katina.
After Decision Day, the pair consummated their marriage, and the reunion special featured Olajuwon sharing how watching himself back on Married at First Sight was a very eye-opening experience and taught him how to become a better man.
Olajuwon proposed marriage to Katina with what appeared to be a diamond ring, and Katina cried tears of joy at the reunion. Olajuwon also thanked his wife for having his back and not leaving him in light of backlash and criticism from show fans, given many viewers thought Olajuwon was controlling and condescending.
On the Married at First Sight: Where Are They Now? special for Season 14, Olajuwon and Katina were finding their new rhythm as spouses. They said they were actually spending too much time together, and so Olajuwon and Katina agreed to spend one night a week with their respective friends or family members.
But Olajuwon gushed about being in love, and Katina was happy Olajuwon had come around to more of a 50/50 partnership.
In late May 2022, Olajuwon posted an Instagram slideshow of photos with Katina and captioned it, "The one who loves you will NEVER leave you, Even if there's hundred reason to give up, They will find one reason to hold on!"
Katina also sweetly wrote to her husband on Instagram around that same time, "I can't wait for what God has in store for us."
"Thank you for growing with me, building with me & loving me. I am so proud of the man you continue to strive to be. Thank you for not giving up on us, and showing up in this marriage every day," she added.
