Early in the film, Martha remembers kissing “a very handsome man” at the Duomo in Florence while Andy was at their hotel on their European honeymoon.

“He didn’t know I was married,” he says of the stranger. “I was a lonely girl hanging out in the cathedral on Easter Eve. It was emotional. I was emotional. Because this was an emotional place. “It was unlike anything I’d ever experienced.”

Martha explains that while she was working as a stockbroker in the late ’60s, she once had a “very brief affair” with a “very attractive Irish man.”

“It was nothing,” he says. “I would never break up my marriage over this.”

Andy told producers that he “didn’t leave” until he left.

“He wasn’t happy at home,” Martha says in the film. “I don’t know how many different girlfriends he had during this time, but I think he had a lot.”

“Young women, take my advice, if you’re married and your husband starts cheating on you, he’s an asshole,” she adds in a previously seen clip in the doctor’s trailer. “Give up on this marriage.”

Later in the film, Martha’s friend Kathy Tatlock recalls rumors that Andy was “having some sort of affair with the girl who did the flower arrangements” at Turkey Hill Farm (the couple’s home in Westport, Connecticut).

“Andy started with it while I was traveling,” he says. “It was like I was making a snack for Andy.”

Martha says she confronted them about the affair. “I threw him out immediately,” he says. “You know, ‘What are you doing?’”

“Andy betrayed me over our property,” he continues. “Not nice.”
