"March 6, 2014, I received a call from Kinetic Content that I was going to be married at first sight. I remember it because it was the day before my mother's birthday," Cortney, who starred on Season 1 of Married at First Sight, told the magazine.
"March 6, 2020 is the day that Sherm got down on one knee and asked me to be his forever."
Cortney, 31, said this day "brought everything full circle" for her.
"God has showed up in such a big way in our lives. I did not know that this is what love felt like," Cortney continued.
"After everything we both had been through, we didn't know it was possible. We are both grateful for our past because it let us to each other, made us grow through some of the darkest times and prepared us for this relationship and a lifetime of love and partnership."
Meanwhile, Jason moved on with British actress and former U.K. reality TV star Roxanne Pallett. Reports the couple were dating first surfaced in August 2019, and they just tied the knot on January 26 in New York.
As for Sherm, he reportedly ended a previous marriage about six months before meeting Cortney and was "skeptical and reluctant" to commit to her at first.

"Early on in our relationship, Cortney and I would stay up into the early hours of the morning talking and connecting on so many levels. I didn't envision having serious talks about my future with another woman any time soon, but here I was," Sherm, 29, told People.
"I hadn't ever enjoyed being with someone as much as I enjoy being with Cortney, and I knew this is how a marriage should be."
Sherm reportedly fell for Cortney fast and so he asked her parents for their blessing to pop the question in December 2019, after which Sherm spent 10 weeks customizing her engagement ring and finalizing proposal details.
"Cortney had mentioned she liked emerald-cut diamond rings, which are not exactly in style right now. I wanted to give her the ring she wanted, and wanted it to be timeless, unique and as complex as the late-night talks we have," Sherm said.
"I planned a trip up to Boone, North Carolina, and had planned to propose in the mountains. As the date got closer, I sensed Cortney was anticipating my proposal... [so] I changed my original plan."
Sherm therefore proposed marriage to Cortney at a hotel room where he was staying for work, only one day before their planned trip to the mountains.
"I asked her to pour us some wine, and she grabbed the glasses without noticing the ring and turned around to me on one knee with a ring pop," Sherm recalled.
"She always said I could propose with a ring pop and that would be enough! She laughed and asked, 'Is this for real?' I grabbed the wine glass while on a knee and handed it to her, and she noticed it this time and said 'Yes!'"
The couple then celebrated their engagement in Boone and are looking forward to getting married and welcoming children together.
"One of the greatest qualities I see in Cortney is her commitment to the partnership marriage becomes. I've come to realize her ideal dream wedding is much more about marrying the right person and much less about the spectacle many modern weddings have become," Sherm told People.
"I couldn't be happier or more excited to marry Cortney and start a family of our own."
Cortney and Jason were married for five years before they split.
Jason got engaged to Roxanne -- who has appeared on several U.K. reality series including Celebrity Big Brother -- in December 2019, only 10 months after divorcing Cortney.
Jason gushed about his new fiancee on Instagram at the time, "When I said you're the love of my life I truly mean that. You get me more than anyone ever has and ever will."
Cortney had initially announced her divorce from Jason, saying they wanted to "move on in different paths" but the makeup artist still had love for her ex and would always have "a special place in [her] heart" for him.
"We asked for privacy this entire time bc we were trying to figure it all out. At one point we thought we were going to divorce in order to date and start all over the right way," Cortney continued.
"We have decided together to move on in different paths, but that doesn't mean we don't have love for each other. He will always have a special place in my heart and life."
Jason subsequently told People in a March 2019 statement he and Cortney had decided to separate "with a heart full of sadness."
"We fell deeply in love, and had very much a fairytale story being married as complete strangers in the docu-series, Married at First Sight," Jason said.
"We both had such an incredibly magical journey together these past few years, making this that much harder to write and even harder to live. These last few months, we asked for privacy to reevaluate things. It has been a very difficult time for me especially with all the rumors, as well as the public wanting updates about our marriage."
Jason added that he and Cortney would "continue to love and support one another" with "a common goal to remain friends."
During their Married at First Sight season, Cortney found it difficult to be married to a firefighter and Jason was dealing with his mother's failing health.
However, the couple decided to stay together at the end of the experiment on "Decision Day."
