She claimed that the Coronation Star punched her several times, however Ryan said he meant no harm and apologised.
Thomas's girlfriend and reality TV star Lucy Mecklenburgh called for Roxanne to be removed from the show, adding that she does not think she is in a "fit" state of mind.
"I was going to ask if you want your washing done but I might shrink them instead" she says as Thomas playfully ushers her into the bedroom.
"I do feel like I got played a little bit and I still feel a little bit upset about that, but at the same time I'm glad I handled the situation the way I did". She has now been reunited with her fiancé and family and thanks everyone for their support during her time in the show'.
Roxanne has demanded Big Brother to kick Ryan out of the house, however they stated that the situation had been dealt with and that Roxanne was safe in the house. "When she said that, I was like, "Woah".
Ryan's family and friends had seen reacting in fury to the claims - going online to defend him.
A Celebrity Big Brother spokesman told the BBC: "Roxanne has made a decision to leave the Big Brother house".
Ryan had tried to apologise to Roxanne for his actions and insisted that it wasn't malicious and that he was "showing my affection".

"Sad to say, from what I've heard, I had a very similar experience with this lady a year ago", Connor tweeted. Pallett then, as fans of the show pointed out, holds her right side as if in pain even though Thomas tapped her on the left side.
Ouch: Asked by Kirstie Alley whether she thinks that Ryan meant to hurt her, Roxanne claims: "It hurt".
The newly evicted Celebrity Big Brother contestant was reportedly told about Roxanne walking out of the house during the interview - and appeared to be stunned by the news.
She also turned other co-stars against Thomas, until they reviewed the footage.
When he was talking about what happened, the soap star broke down and admitted that he felt, "Really, really really bad".
Among them was former chief prosecutor Nazir Afzal, who said the actress "clearly has issues and needs help". My life's in tatters'.
Later on, in the live feed, Ryan screamed out: "F***ing get me out of here now!"
The reason for Roxanne's seemingly unreasonable reaction to Thomas's playfighting could lie in her allegedly traumatic previous relationship.More news: Widow and children lead mourners at service for John McCain
