The Bigamist by Ethel Mills

They were difficult days which followed. Pamela went about as usual, but she looked white and worn, and evidences of sleepless nights and much weeping disfigured her eyes. Arnott, unequal to the tension, decided on a brief separation, and took a trip round the coast. His absence -- it was the first time he had gone away without her since their marriage -- might bring home to her some realisation of what life would be like if they finally parted. Perhaps, when she was alone, when she missed his actual presence, she would relent. If, when he returned, he found her still obdurate he would broach the subject of a more complete separation.

He did not seriously believe that she would bring herself to the point of parting irrevocably. As things were, it was more difficult to part now than it would have been in the first shock of revelation. She had had time in which to adjust her mind to the altered conditions, to be called upon to readjust it, to do so late what she had felt she ought to have done at the beginning, and had failed to do, would add a fresh humiliation to the former difficulty, would make the difficulty greater. He felt fairly convinced that she would not willingly leave him, and he meant to force her into compliance by holding out this suggestion as the only possible alternative.
