If you remember that chaotic dinner scene from episode three, then you know Lauren and Nate were one of two couples to cut their time short on "The Ultimatum." In a surprising turn of events (that followed after another bombshell proposal), Nate popped the big question to Lauren before she could pair up with Colby. The two got engaged and left the show as they no longer needed to go through the entire experiment.
During the reunion, the couple updated viewers on what happened after they left. Nate, who was very vocal about wanting kids, proposed to Lauren without knowing whether or not they'd ever start a family. "It was me coming to the realisation that I would rather spend the rest of my life with her and not [have] kids, than having to find someone that's 70, 80 percent, at best, of what Lauren is to me and have a kid fill the remaining 20 percent," he explained of his decision to propose.
After Nate's proposal, he and Lauren said agreed they still had things to figure out in their relationship, so they sought out "expert advice" from a therapist. They also shared that they didn't feel like the show was a good fit for them because they only had one issue to solve: having kids together. In the end, the two revealed that they finally agreed to have one child, so they're still going strong.
