When Clark and Valerie Tate decided to end their year marriage, they opted to do things a little differently: Though they no longer consider each other husband and wife, they still live under the same roof in order to raise their son Jonah together. In the Nightline interview above , the San Francisco couple explains why divorce was never an option for them, how the decision has affected their young son, and what it’s like to date when you’re still technically married. With two divorces behind him, Clark knew how emotionally and financially draining the legal process could be. Dragging his family through that was the last thing he wanted to do. And so they didn’t — not much, anyway. Today, the pair continue to raise their son together and maintain joint assets, but sleep in separate bedrooms and date other people — with a few unwritten dating rules for their son’s sake: The pair only introduce Jonah to people they’re serious about and try to have their adult sleepovers elsewhere. But most of it is private time spent elsewhere. Though Valerie is in a serious relationship with a man named Joseph in the clip above, he stops by the house and even goes to dinner with the family , Clark admitted that explaining the couple’s living arrangement to dates can be a tough sell.
