It remains her only marriage.
Martha has been frank that Andrew was repeatedly unfaithful during their time together.
Although, she has also admitted to cheating herself early in the marriage.

She later added, “he’s a piece of s***.”
The couple dated and married when Martha was still relatively young, only 19.
At the time, Andrew was a student at Yale Law School.

The company would later go defunct and be sold to Abrams Books in the late 1990s.
The same publishing company where his wife, Shyla Nelson, is the CEO and President.
(The marriage to Nelson is Andrew Stewart’s third.)
Perhaps, the two will connect at some point in the ensuing years.
