By the end of 1934, Edward was irretrievably besotted with Wallis, finding her domineering manner and abrasive irreverence toward his position appealing; in the words of his official biographer, he became "slavishly dependent" on her. According to Wallis, it was during a cruise on Lord Moyne's private yacht "Rosaura" in August 1934 that she fell in love with Edward. At an evening party in Buckingham Palace, he introduced her to his mother—his father was outraged, primarily on account of her marital history, as divorced people were generally excluded from court. Edward showered Wallis with money and jewels, and in February 1935, and again later in the year, he holidayed with her in Europe. His courtiers became increasingly alarmed as the affair began to interfere with his official duties.
