The couple had high hopes for their relationship after their wedding day, but things started going downhill during the honeymoon, and then Domynique decided on Day 12 of marriage that she wanted a divorce.
During the March 1 broadcast of Married at First Sight: Afterparty on Lifetime, Domynique watched back a Season 16 clip of Mackinley sharing the news of their divorce with the rest of the cast.
"Me and Dom have made the decision to get divorced," Mackinley announces at the group gathering in their apartment building.
When asked what happened, Domynique explains of her husband, "He had made a few comments that made me feel like he was not happy."
"I don't fully agree with that," Mackinley counters. "I was 100 percent blindsided that you asked for a divorce."
Afterparty host Keshia Knight Pulliam asked Domynique how she felt listening to Mackinley's announcement about the end of their marriage.
"I mean, I can't cuss right? That was a load of sh-t! It's a load of sh-t," Domynique insisted.
Keshia praised Domynique for being honest, and so Domynique continued, "Once again, he is saying something to other people that is the opposite of what he has told me."
"I sent him a text after the meeting with Pastor Cal [when I had asked for a divorce] saying, 'Hey, let me think about it. I'm not completely closed off to continuing on with the process. But in the moment, there's just so much pressure,'" she recalled.

But Domynique felt she had been as patient as possible, and she said she wanted to end their negative relationship before it became very "toxic."
When the sparring spouses gathered with their fellow cast members, they were asked if there was any hope for reconciliation.
"Maybe," Domynique replied.
But Domynique later confirmed with Mackinley that she had just said "maybe" due to peer pressure and didn't mean it.
"[That's] a young woman's game, and that's what Dom plays," Mackinley vented to the cameras.
Domynique then told Mackinley that although things didn't work out, they could remain friends. But Mackinley snapped that he didn't need another friend in his life.
Mackinley said while he and Domynique weren't a perfect match, he had been prepared to give their marriage time and effort -- which were two things he didn't receive from Domynique. He believed Domynique simply wasn't ready for marriage.
