The 35-year-old actress admitted to Emma that she felt she was the "most hated girl in Britain", and that she was anxious about her future.
Willis questioned Pallett on the timeline of her story, before saying: "You could have ruined him".
An emotional Roxanne replied: "It's a lot to deal with".
In these latest string of tweets Lucy Pargeter who plays Chas Dingle on Emmerdale had more than enough to say on the situation and references past encounters with Roxanne.
"I am scared about the future". She said: "I don't think I'll ever forgive her".
The caring mum also said she was anxious about how the incident will affect her son's mental health when he comes out of the house.
"I'm human and I made a massive, massive, awful mistake".
The four-minute long interview was prerecorded, as Channel 5 decided not to put Roxanne in front of a live audience. How it felt when he did it, it hurt. I can't prove a feeling.
'Everything in that house becomes heightened, a look, an action, a comment.
A spokesperson for Chesterfield Borough Council - which owns and manages the Pomegranate Theatre - said: "We are aware of the public and media reaction to Roxanne Pallett's recent appearance on Big Brother". I don't want to see her again because of all this. "But we're also thinking, 'She's here at the centre of a kind of maelstrom, it would be fantastic if she hadn't thought through what she was going to say'". "I hope that people can forgive me, and Ryan can forgive me in time".
"I convinced myself that it was done with malice. It wasn't - I know it wasn't now".
She continued: "Seeing the footage of Ryan in the Diary Room all distressed".
"I fully agree and understand with every single person's reaction and perceptions to that".
She added: "I felt, genuinely, disturbed by the fact that somebody had invaded my personal space. I was wrong, massively wrong". Emma did not hold back in this interview (unlike Jeremy Vine earlier on in the day) and asked her the hard questions, to which she seemed to have no answers.
