Stewart and her husband both had affairs during their marriage.

Stewart speaks at length in “Martha” about the fallout from her marriage to Andrew, saying he cheated on her repeatedly while they were together. They were married from 1961 to 1990.

In the documentary, Stewart said that one of her ex-husband’s affairs was with a woman she hired to do the flower arrangements at Turkey Hill. When the girl lost her apartment, Stewart invited her to move into the barn on her property.

“When I was traveling, Andy started her,” Stewart said. “It was like I left a snack for Andy.”

“Young women, take my advice: If you’re married and you think you’re happily married and your husband starts cheating on you, he’s the piece of shit,” she added. “And consider him a piece of shit and get out of this marriage.”

At this point in the documentary, Cutler interjects and asks Stewart if she had an affair early in her marriage.

“I don’t think Andy ever knew about it,” Stewart says.

“He said he knew about it,” Cutler said. “He said he didn’t walk away from the marriage until you told him you had already walked away from the marriage.”

“Oh, I don’t think that’s true,” Stewart replies.

“But what happened, you had an affair?” Cutler asks.

“I had a very brief affair with a very attractive Irishman,” says Stewart. “I would never have broken up a marriage for that. It was nothing. It was like the kiss in the cathedral.”
