Alleged murderer Margaret Anne Otto said her affair with co-accused Bradley Scott Purkiss made her feel "special and respected", a court has heard.
The pair are jointly charged with the murder of Ms Otto's husband Dwayne Robert Davies.
Both have pleaded not guilty.
Mr Davies was last seen on May 26, 2017, and his body was found a week later in a shallow grave at Levendale.
In a video interview with police on May 30, 2017, played to the jury, Ms Otto said no one knew of her affair with Mr Purkiss, including her husband Dwayne.

Ms Otto had previously told police about how her relationship with her husband had deteriorated and she wanted to leave him.
Ms Otto said Mr Purkiss had told her he wanted to show her what it was like to be loved and respected.
"It wasn't really physical. The emotional connection was the biggest thing for me," Ms Otto said in the video.
"He was telling me how beautiful and gorgeous I was.
"[He] made me feel special and respected even though it was the way it was and I felt bad because of Jill [Mr Purkiss' partner]."
Ms Otto said her relationship with Mr Purkiss made her realise what she was missing out on in her marriage with Mr Davies.
She said in late 2016 she and Mr Purkiss had a conversation about what life would be like if the two were together.
"[It was] could it really be? Is this how life should be?" she said.
"That's what I wanted. I wanted out of this."
Ms Otto said Mr Purkiss and his partner Jillian Roberts had both offered to help her leave Mr Davies.
"I thought he was going to save me in the context of getting me out of there," she said.

Wife told she was 'free' of husband
Ms Otto said Mr Purkiss had come to her Risdon Vale home shortly after 10.45pm on the night Mr Davies was last seen.
This contradicts a statement earlier in the interview when Ms Otto said she first spoke to Mr Purkiss after Mr Davies went missing via a phone call at 4am.
"I didn't expect him. I was shocked to see him," Ms Otto said.
"He said 'you're free and [Mr Davies] will never be a problem'.
"I had a gut instinct whatever happened was not nice."
Ms Otto said Mr Purkiss did not tell her he had killed her husband.
"He didn't say he did but he didn't say he didn't," she said.
Ms Otto said she would have been relieved if Mr Davies had committed suicide.
"To murder somebody? To ask someone to murder somebody. No," she said.
"I can see that the information 'life would be easier if [Mr Davies] was dead', how [Mr Purkiss] could have taken that."
The trial before Chief Justice Alan Blow continues.
