Big Brother contestant Jonathan is expected to quit the show on Thursday.
The 49-year-old Londoner reduced the normally boisterous housemates to silence and tears on Wednesday by pouring out his heart about his plans to make his exit.
The self-made millionaire, who runs a media agency, told Big Brother he would sleep on his decision before leaving the house on Thursday morning.
Jonathan listed a number of items that he had put on hold or "risked" to join the reality TV show, adding: "I've been so reckless to do this".
He said being in the house had made him realise that he had been looking for acceptance and assured his housemates his decision to go was nothing to do with any of them.
"I feel like I've won Big Brother because I've got something out of it," he added.
By the end of his heart-to-heart talk, the usually noisy housemates had been stunned into silence and both Carole and Charley were crying.
Jonathan describes himself on Big Brother's official website as the "luckiest f***** on the planet" and a "lazy git".
Meanwhile, blonde twins Sam and Amanda won a party for themselves and two of their housemates on Wednesday by "proving" they were telepathic.
Amanda drew a picture of a man with a beard and in a separate room Sam drew a bearded Santa Claus - which was good enough for Big Brother.
