Mackinley's mother made it known on the show that she wasn't happy with her son's "crazy" decision to wed a complete stranger. She said she'd prefer to see Mackinley date a woman for two years, get to know her, and then make an educated and well-informed decision to tie the knot.
But according to Mackinley, his mother was actually desperate to put a stop to her son's risky arranged marriage.
While Mackinley's mother was extremely hesitant and skeptical of her son's choice to participate in this extreme marriage experiment, Mackinley thought his mom's conversation with Domynique at the wedding was positive overall.
Mackinley -- who assured Keshia that his mother wasn't bothered by his interracial union at all -- said his mother even asked for Domynique's phone number by the end of the night.
Mackinley explained how he's "very family-oriented" and his mother has had a good relationship with all of the women he's dated in the past.
"She takes their side more than mine in relationships," Mackinley noted.
Mackinley revealed on the first Afterparty episode, which aired earlier this month, that he almost backed out of the doing the show because he was seeing another woman.
"I had a girl that I was talking to," Mackinley admitted. "But I don't know that we were on the same path as far as marriage, and that's something I'm looking for."
Keshia asked at the time if there was a scenario in which Mackinley may have opted out of marrying a stranger, and he replied, "One hundred percent. I was unsure that I was going to do it and, like, follow through."
Mackinley said he was unsure whether to commit to the extreme experiment because he and this pre-show mystery woman "had a really good connection."
"But yeah, I went in the opposite direction," he confirmed.
Mackinley told his bride that she looked "gorgeous" at first sight, and Domynique determined that Mackinley is a "handsome" man with a nice smile.
Domynique's loved ones told Mackinley that he had a fierce but caring, outgoing, and selfless woman on his hands. Mackinley learned Domynique is a bubbly woman and Tomboy at heart who loves dancing, fishing and playing volleyball.
Mackinley's family and friends advised Domynique to buckle up because her husband enjoys driving fast cars and taking adventures. While he's a thrill-seeker at heart, Domynique was assured that her husband would like to stay home sometimes and just sit on the couch with her and watch movies.
Mackinley was optimistic he and Domynique would fall in love and they'd have "a bunch of babies" together and "live happily ever after."
While Mackinley and Domynique got off to a great start, Married at First Sight previews suggest their relationship is going to crash and burn.
"I was one hundred percent blindsided," Mackinley tells his friends in tears. "I was not whom she was looking for."
Domynique is then shown walking down the hallway of her apartment complex with a big box of her things and tears in her eyes.
