After her mother died in 1893, Gilman decided to move back east for the first time in eight years. She contacted Houghton Gilman, her first cousin, whom she had not seen in roughly fifteen years, who was a Wall Street attorney. They began spending a significant amount of time together almost immediately and became romantically involved. While she would go on lecture tours, Houghton and Charlotte would exchange letters and spend as much time as they could together before she left. In her diaries, she describes him as being "pleasurable" and it is clear that she was deeply interested in him. From their wedding in 1900 until 1922, they lived in New York City. Their marriage was nothing like her first one. In 1922, Gilman moved from New York to Houghton's old homestead in Norwich, Connecticut. Following Houghton's sudden death from a cerebral hemorrhage in 1934, Gilman moved back to Pasadena, California, where her daughter lived.
