Transcript for 'Married at First Sight' Couples, One Year Later
who said no to marriage as we know it and yes to so-called relationship gurus who believe they could pick anybody's perfect partner. A controversial experiment, to be sure. But you may be surprised at some of the results. What happens after you meet your future spouse for the very first time at the altar. Here's ABC's Lindsey Jennings. Cheers. Yes. Okay. Just relax. Reporter: Three beautiful brides, getting ready to walk down the aisle. I'm scared. Reporter: And into the arms of their waiting grooms. Woo! Let's do this! Reporter: Everything is perfect. The dresses, the flowers, the champagne. But there is just one catch. I think I just made the worst decision of my life. Reporter: They're about it marry someone they have never met. Courtney Hendricks, meet Jason per on. Nice to meet you. Reporter: The brides and grooms total strangers. Do you take him to be your husband. Reporter: And their first words to each other? "I do." Yes. Reporter: These six brave souls agreed to this extreme social experiment last March for the reality show "Married at first sight" allowing four self-proclaimed relationship experts to find their perfect match. After five weeks, the couples have a choice. To get a divorce or stay together. I want to stay married. I want to spend the rest of my life with you. We have decided to get a divorce. Reporter: For the two couples who stayed married, the cameras never stopped rolling. Now, a new spinoff show showcases their first year of marriage. Made it! Reporter: Back on their big day, 32-year-old Doug henner and 28-year-old Jamie Otis weren't seeing eye-to-eye. Couldn't have been happier seeing someone just absolutely gorgeous. This is the worst feeling. And I just happen to be not attracted to the guy. I feel so bad. Reporter: And the days after that -- honeymoon. We were married two weeks and he lied to me about something really, really silly. He used to smoke and he had a cigarette. Reporter: A small marital spat that highlighted deep trust issues. I don't know. For me, I was like two weeks in, you're lying about that, what are you going to lie about a year later? Reporter: Lucky for them, there was help on hand. You learn how to argue, and how to talk when you're upset. And how someone will receive, you know, what you're saying and how you say it. We're very lucky we have a chance to speak to the experts. Reporter: As well as game tape to review. We also have a chance to reflect back and see how we were in these moments. Our whole family. Reporter: The two decided to tough it out. Even moving to a new home. Hoping they would fall in love. It's got to be hard to hear I'm not in love with you. He's like, have you ever been in love with someone in a month? Give it time! Sorry, lady. This is mommy and daddy time. Reporter: Unlike Jamie and Doug's rocky start, Courtney and Jason felt an instant connection. We played a lot of 20 questions. We stayed up a lot, like, talking, and didn't sleep a lot. And that's really how we got to know each other. Didn't sleep because you were talking. Well -- sometimes. Well, I'm just going to go drink my coffee. Reporter: But married life soon became very real for the aspiring makeup artist and her firefighter husband. We have been under so much stress so we're trying to get settled into our apartment, Jason is in the academy. I can only handle this for so long. Crap is everywhere. Reporter: Things reached boiling point when Courtney lost her job. We're so awkward right now. This is really uncomfortable. Like sitting here in silence. And I don't know what's wrong. It's like this tornado just happened. You know, the whole job thing. Reporter: They called in the experts. I think, honestly, the honeymoon stage is gone at this point. Reporter: . Courtney and Jason are at the brink. They both lost a lot of the connection they had. And in order to reconnect, they have to keep remannsing and wooing and keeping their relationship hot. Because if they can't find quality time, their marriage won't survive. Did your mom decorate that? Yeah, my mom was like a master. Reporter: Ultimately, it was a family tragedy that brought this couple together. My mom had lung cancer, and is she passed away. I kind of wish you would have got to know her. If it wasn't for Courtney, I don't know. She supported me. Where there is dark, you know, there is light. And Courtney is my light. And she shined on me through this whole thing. Reporter: For Jamie and Doug, love did eventually blossom. I love it! When did you fall in love? Can you pin point it? Honestly, it was a long transition. For me personally, it takes time. I think it was a build-up for me. There was a lot of small experiences where I just learned I could trust him and he would show me he respected me. The simple fact he waited to have sex with me, you know, until I felt like I was ready. Reporter: They waited two whole months. Thank god she worked nights so I had nights alone. Reporter: The marriage is going so well, but Jamie may be getting carried away. Making the money so we can have a baby? Yeah. You're really into this whole baby thing, huh? You're not? I mean, eventually. I just -- maybe it's because I do feel pressured. Reporter: For now, Doug just wants to spend time with his new wife. We both want kids. I would rather have that strong foundation first, before we introduce, you know, a baby into the mix. Reporter: Both couples now say they can't imagine life without each other. How do you explain this? Did the experts just get it right? At first, I said this is ridiculous. They're going to fix me with my perfect match? The proof is in the pudding. There is a difference between what you need and what you want. And maybe sometimes we didn't know what we needed. Reporter: Turns out, what they needed was patience. And invaluable guidance from the show's relationship experts. Something maybe we could all use. Well, I had no idea I needed to grow up until I literally, like, watched Dr. Logan say it on TV. And I'm like, oh, that makes sense. And I saw, like, a change in myself. But you see yourselves being married for decades to come. Honestly, I can't see a future without her. Ditto. The experiment is to be continued. No, I'm in it for the long run. You better be. Reporter: For "Nightline," I'm Lindsey Janice in New York. "Married at first sight" airs Tuesday nights on FYI network,
