Thea had been thinking of divorce ever since James got arrested.
She planned to divorce him after he was found guilty.
She was not even twenty-eight years of age and was in the prime of her life. She did not wish to wait for James for the rest of her life.
She would be old by the time James got released from prison and did not wish to live with regrets.
She knew she had let James down.
It was because of her that James did not manage to suppress his desire and went down the wrong path.
