In 1965, after leaving UA, Applewhite moved to Houston to serve as chair of the music department at the University of St. Thomas. His students regarded him as an engaging speaker and a stylish dresser. He also became a locally popular singer, serving as the choral director of an Episcopal church and performing with the Houston Grand Opera. In Houston, Applewhite was briefly openly gay but also pursued a relationship with a young woman, who left him under pressure from her family; he was greatly upset by this outcome. He resigned from the University of St. Thomas in 1970, citing depression and other emotional problems. Robert Balch and David Taylor, sociologists who studied Applewhite's group, speculate that this departure was prompted by another affair between Applewhite and a student. The president of the university later recalled that Applewhite was often mentally jumbled and disorganized near the end of his employment.
