In Unhitched, longtime couples tell the stories of their relationships, from romance to vows to divorce to life afterward.

The marriage of Katrina Lamb, who was then Scott Lamb, and Wendie Lubic had highs and lows but suffered from a deeply held secret: Katrina, born male, always knew she was transgender but it took many years and three marriages for her to live truthfully. Katrina, 53, and Wendie, 54, were 24 when they married.

Where did they grow up?

Wendie in Washington in a Reform Jewish household with parents who were professionals and traveled widely for work. Katrina in happy homes in Thornwood and Katonah, N.Y., then in Australia from age 12 to 18; her father was in finance, her mother is an artist and active in her community: “We went to my dad for permission, we went to my mother for comfort,” Katrina said. She knew she was “in the wrong body” from age 6, but also knew, even at that age, that that would never be revealed.

How did they meet?

In 1985 at a Halloween party in New York City. Wendie, then a journalist, was working for Newsweek. Katrina, then still Scott, was working for Morgan Stanley. They felt immediately connected and shared a sense of humor. Wendie could quote Monty Python, which made Katrina announce “this was the woman I am going to marry.”
