The 15-Year Love Affair That Ended in a Bedroom Confession

Martha Stewart and Charles Simonyi’s relationship was a true partnership of equals, a union between two of the most successful and brilliant minds in their respective fields. Their bond began in the early 1990s, following Stewart’s divorce from her first husband, Andy Stewart.

The 15-year romance was characterized by private jets, luxurious trips, and intellectual camaraderie. Simonyi, a pioneer in software development, and Stewart, the reigning queen of domesticity, seemed an unlikely but complementary pair. Their relationship was so serious that Simonyi even flew a special meal prepared by Martha, including takeout from Alain Ducasse, into orbit with him during his first space flight in 2007.

Crucially, Simonyi stood by Stewart through one of the most challenging periods of her life: her five-month prison sentence in 2004–2005. This unwavering support cemented their image as a resilient power couple, leading many to believe a marriage was inevitable.

However, the relationship took a dramatic and sudden turn in 2008. In a shocking revelation detailed in the recent Netflix documentary *Martha*, Stewart recounted the moment Simonyi delivered the news. While they were in bed together, Simonyi told her he was marrying a woman named Lisa and that her parents wanted him to cut ties with Martha.

Stewart’s response to the abrupt, cold-hearted nature of the announcement was candid. She referred to the breakup as her "second 'divorce'" and lamented, "What a stupid thing to do to someone that you actually cared about." The revelation was particularly painful as it came just a few years after her release from prison, marking an unexpected and distressing end to her last major public relationship.

Lisa, who was 32 years younger than Charles Simonyi, married the billionaire in a beautiful ceremony in Gothenburg, Sweden, on November 22, 2008. The significant age gap between the couple immediately drew attention from the media and the public, especially given the history with Martha Stewart, who is only seven years Simonyi's senior. Lisa is the daughter of a Swedish millionaire, and her family background provided a stable, wealthy foundation for her life with the tech mogul.

The couple quickly started a family, and they now share two children. Charles Simonyi, who is now aged 77, remains married to Lisa Persdotter. Their life together includes philanthropic endeavors and managing Simonyi's vast fortune, which is largely derived from his pioneering work on the Microsoft Office suite—specifically Word and Excel—and his early stock options.

Before his second space flight in 2009, Simonyi promised his new wife, Lisa, that it would be his last journey into space. This gesture underscored his commitment to his new family and his shift in priorities following his marriage. The Simonyi family maintains a high-profile but relatively private life, balancing their immense wealth with their philanthropic work and raising their children.

The Enduring Legacy of a Billionaire Love Triangle
