Who is Martha Stewart’s ex-husband whom she cheated on? Meet Andrew — who married her assistant

Martha Stewart married Andrew Stewart in 1961 but their love eventually boiled over for good.

The couple welcomed their daughter, Alexis Stewart, in 1965 before separating in 1987 and officially divorcing in 1990.

In 1995, Martha’s mother, Martha Kostyra, told People that the acrimonious divorce left her daughter “badly wounded.”

Kostyra added: “I don’t think she’ll ever get over it.”

Decades later, in 2020, the 83-year-old opened up to the outlet that she had moved forward despite the pain.

“Getting divorced was a terrible thing for me, because we were the first to divorce in my family,” confessed Martha. “And that we haven’t spoken since the divorce is even more painful. But I’m very strong, and I’m very motivated to get on with life.”

“I have survived the rigors of time, of marriage, of childbearing, of building a business from scratch. I have survived very nicely, and I think I make the most of it.”

During their relationship, Andrew and Martha spent time revamping old homes. People reported in 1995 that the pair spent the early weekends of their marriage “restoring a schoolhouse in the Berkshires.”

Andrew shared in 1995 during an interview with People that he regrets how he and Martha raised their daughter, stating, “I think we did a poor job as parents.”

“We were too involved in our professional lives and fixing up the house. We were always making the home into a mythological place. But it wasn’t a home — we didn’t spend enough time with Lexi.”

He called his estrangement from Alexis “a source of tremendous pain.”

Following Andrew and Martha’s divorce in 1990, he married Robyn Fairclough in May 1993.
