Transcript for Married Couple 'Uncouples' in Special Ceremony Instead of Divorce
When a marriage crumbles, does it have to be horrible and horribly expensive? Not for the couple you're about to meet. They say they're one big happy family under one roof while dating on the side. Here's aditi Roy. Reporter: This couple is holding a ceremony. Let's begin. Reporter: Renewing their Vo vows? Not exactly. We're releasing these rings. Reporter: Today, in a new age ritual you may only find in San Francisco, they're handing them back over and uncoup. They no longer consider each other husband and wife, but they will continue to live together in order to raise Jonah. Is there any sense of mourning or loss doing this? No. It's actually exciting. We've grieved a lot of our relationship so long ago. Reporter: But that isn't the way it usually works. In movies, divorce often gets ugly. Get out of the car. Okay. Reporter: No wonder in real life, when gwynethp altrow and her husband decided to uncouple earlier this year. Your wife says, I want to date other people. What goes through your mind? I remember initially being shocked, and then, that sounds interesting to me, too. Reporter: So, this is Clark's room? And this is your room? Their relationship wasn't always like this. What was your wedding like? It was magical. Reporter: It was her first time walking down the aisle, and Clark's third. I was grieving the loss of my father. And had some depression around that. With all that, I started to withdraw. Reporter: Their young marriage was failing. Why not just part ways, go through divorce like so many couples? I've been down that road before. Reporter: So, even a separation wasn't on the table. No. We weren't considering changing the structure of our family. Reporter: Centered around Jonah, who they were determined to protect. You have friends with parents who are divorced. What is that like for them? They're sad most of the time, and they are sometimes gloomy when I come over to their houses. Reporter: How would it make you feel for your parents to get a divorce? It would make me sad. But if they were still friends, we would be fine. Children don't understand what's happening, they feel as if it may be something they did wrong. Reporter: And it's not just emotional, it's financial. Couples pay an average of $50,000 to resolve contested divorces. That's according to this documentary. That's what I charge. Reporter: They decided not to go that route. Instead, they've been experimenting with an open marriage. For the last few months, Valerie has been in a serious relationship with a man named Joseph. It may seem weird for a wife to have a boyfriend, but they have unwritten rules for dating. What's going on? Just getting ready. Reporter: Do you sleep over with other people here? Well, we give each other private time. But most of it is spent elsewhere. How are you? Good. Reporter: And the most important rule, they can only introduce serious partners to their son. What is that like for you? It's fun. It's been seamless having all of us hang out. They like each other, so I feel fortunate that way. Reporter: Tonight, they're all meeting up for dinner together. These longtime friends struggled to get to this point in their relationship. But to an outsider, there's still a potential for awkward moments. If one person feels like the other is pushing them into the situation, it won't work. Reporter: You grew up in traditional families. Is it tough for them to accept this? They wanted us to put it in one box or another. Are you going to get a divorce to stay together? It's difficult to grasp. Reporter: Clark says it's difficult to explain this to potential dates. He says getting married a fourth time isn't in the cards for him, Valerie says it could happen. I think we're through the tough stuff. Questioning jealousy, insecuri insecurity. What are we doing? Yeah. Reporter: They've figured out how to be happy as a family. And a legal divorce is not on the horizon, at least not for now. Next, the last patrol. A shell-shocked band of brothers
