"unhappy marriage and separation"

Gould's wife Muriel accused him of being a violent, unstable drunk who made unreasonable sexual demands upon her.  Gould denied this charge, but did describe himself as a "mental sadist".  He was prone to terrible depressions, and his absolute focus on the Harrison clocks did not help conjugal relations.  To complicate matters further, Muriel was having an affair with a female dancing teacher, Vivian Gurney.
