A husband with enough status to be worth marrying, but not so much status that he could usurp her position as head of the family? An heir to carry on her family's name after she grows old? The ability to tell multiple suitors only interested in her money and power 'back off, I'm married now'? The fact that, since she is wedded and has a son, she is now considered 'more legitimate' in the business world and people take her more seriously?

Really, she probably got the better end of the deal here.
