Fitness instructor Jayne Meyler asked to be given the push from TV's Survivor island because she wanted to be with her young son.
The 47-year-old, from Steyning, said she told fellow tribe members she was happy to leave because she was missing seven-year-old Warwick.
She said if she had not made it clear that she wanted to leave, they would have opted for barrister's clerk Adrian Bauckham, whom she called a "wuss".
Viewers saw her booted off the island last night with each of her team-mates voting her out, including her arch-rival Charlotte Hobrough, 24.
Charlotte was seen branding her "the pain" and claimed that she had called her "a dog".
But Jayne refused to bite back, claiming Charlotte had made the insults up.
"I didn't plot and I didn't bitch," said the trainer and sports masseuse.
"Psychologically, I couldn't really work her out. She's confused. I'm a woman's woman - I enjoy women's company.
"I bond with the girls I teach. It was a great surprise to me that I couldn't win her over really."
Married Charlotte had a fling with Adrian during filming and Jayne said the pair would often disappear on errands.
She said: "They spent a lot of time together - but I didn't actually witness any lips on lips.
"I feel Adrian would have done a lot better without Charlotte's influence. I think he was besotted by her and would have done almost anything."
In last night's show Adrian was seen admitting that he would use his mobile phone to get his mother to bring him breakfast in bed.
Jayne said: "I think that if he was on the island on his own he'd have either starved to death or been frightened to death."
She was the fifth of the 16 Survivor contestants to be evicted from the island and viewers saw how she was missing Warwick.
"I was missing my son so badly - what was the point of hanging around to be picked off when I wanted to be with him?"
She told colleagues Andy, James and Simon that she wanted to go "and that was it - I was highly relieved".
She and Warwick both burst into tears when they were reunited. Jayne said she realised that heading off for the island and being parted from her son was a mistake as soon as she set off.
She said: "Even leaving the airport, looking at his little face, I thought, 'What the hell am I doing?'."
