Rachelle Yeo, allegedly stabbed to death by her lover Paul Mulvihill, became engaged to her boyfriend Paul Maher in Byron Bay in the last weekend of July 2011.
On the Monday, Ms Yeo, 31, met Mr Mulvihill in a Brisbane park and told him she wanted to continue their affair, despite her engagement.
Mr Mulvihill is charged with murdering Ms Yeo inside her North Curl Curl unit about 8pm on July 16, 2012.

He has pleaded not guilty, claiming he stabbed her in self-defence after she attacked him.
Taking the stand for the first time in his trial, Mr Mulvihill said the couple decided to keep on seeing each other.
"She said, 'Paul, I'm in love with you. I have been for a while,' " Mr Mulvihill told the NSW Supreme Court on Tuesday.

"I said I was in love with her as well."
Mr Mulvihill married his wife, Theresa, in 1996 and they have three children.
In the 1990s, Mr Mulvihill played rugby union for Gordon and NSW and played rugby league in Sydney and Queensland.

He and Ms Yeo began an affair in late 2010 when they were both staying at the Courtyard Marriott hotel in North Ryde for their work at pharmaceutical company Sanofi-Aventis.
Under questioning from his counsel, Kate Traill, Mr Mulvihill said that, over the next few months, he was in daily phone contact with Ms Yeo.
They would regularly spend the night together at hotels where he was staying as part of his role as a national pharmacy development manager.
He said Ms Yeo called him at his Gold Coast home early on the Monday morning after the Byron Bay weekend to tell him she was engaged. They met that afternoon.
"We spoke at length about what that meant for our relationship," Mr Mulvihill said.
"She said, 'Paul I don't want to stop seeing you. I want to continue our relationship,' " he told the jury.
"I said I wasn't sure it was the right idea ... but we decided mutually that we would continue the relationship."
Earlier in the trial, Ms Yeo's father Roger said his daughter referred to Mr Maher as "Paul one" and Mr Mulvihill as "Paul two" when she spoke to him about her relationships.
Theresa Mulvihill listened to her husband's evidence from the public gallery.
The trial continues.
