Well, why does one usually marry? She loved him and he loved her. In the Victorian Era, a lady and gentleman were not to be left alone unless they were engaged. Eleanor and Franklin got away on a walk alone and he proposed. They kept their engagement secret for a year, as requested by Eleanor's grandmother. And Theodore Roosevelt gave Eleanor Roosevelt (soon to be Roosevelt Roosevelt) away.
Eleanor Roosevelt and Franklin Roosevelt had a unique marriage. You should read the book, Franklin and Eleanor: A Marriage Ahead of its Time.
