A woman who claimed to have an affair with Lloyd Rayney during his disintegrating marriage to Corryn told police their liaison started as a "gambling friendship" and developed into a sexual relationship that lasted more than three years.
But the woman, whose identity has not been released in Mr Rayney's wilful murder trial, said the barrister ruled out leaving his wife despite his strained marriage.
"He never spoke nicely about Corryn … and he would say that they argued and didn't get along," she said in a police statement from late August 2007 that was made available in the Supreme Court trial yesterday.
"Lloyd talked about how he wished he had met me 10 years earlier and expressed his love for me but his position was that he wouldn't leave his wife.
"He said that he believed that his marriage was the only way to retain full custody of his children and he did not want to disgrace his family by divorcing Corryn."
Prosecutors claim Mr Rayney killed his wife on August 7, 2007, after she threatened to expose his womanising and gambling as the pair headed for a bitter separation.
In her statement, the woman described how she and Mr Rayney began with a "gambling friendship".
By the time of a Christmas party in 1999, she had feelings for Mr Rayney. "I knew I was impressed by his status," she told police.
The pair had kissed after the party, with Mr Rayney telling her he found her attractive but was married and could not make any "promises", she said.
But the pair met again and an affair began.
"I thought I was in love with Lloyd," she said in the statement. "From that point on a sexual relationship started with Lloyd.
"He would come around to my unit probably two or three times a week and we would be intimate."
She had come across Mrs Rayney twice - on one occasion at the Australia Day fireworks.
"Lloyd introduced me to his wife and children and I felt very deceitful talking to them," she said.
The woman, who noted Mr Rayney's gambling had become problematic, said the affair ended in 2003 before Mr Rayney left for Bermuda.
She said the last time she saw Mr Rayney "he came up and shook my hand and said it was nice to have worked with me".
She told police she had been offended by his "curt" goodbye.
She told police Mr Rayney had been aware she was also having a brief sexual relationship with another man.
A man with whom Mr Rayney's defence team claims his wife had "more than a friendship" is scheduled to give evidence today.
But a decision on whether he can be publicly identified will not be made until Thursday, after an order suppressing his name was challenged.
