Katie, 37, and 42-year-old Pete have never revealed they real reason behind their divorce, but their feuding has gripped fans ever since.
Now, for new show Katie Price: In Therapy, the former glamour model has stressed that there was no third party involved.
Speaking to Dr Claudia Bernat, Katie said: "I thought that we could have been together forever. I idolised him and he did me, definitely."
In the wake of their split, it was reported that Pete had suspicions about Katie and her horse trainer Andrew Gould. But the mum-of-five stands by her insistence that their relationship was strictly professional.
She continued: "He thought something was going on between me and my horse trainer and I alway said nothing was going on with my horse trainer.
"I loved Pete. I'd never have done anything behind his back or anything like that."
Katie is now happily married to personal trainer Kieran Hayler, but she made the sad revelation that she often thinks men are with her for her money.
"I'm 37, I've been married three times, I've got five kids by three different guys - if I put that on a dating site, would anyone really come back?
"No, they wouldn't. Now let me add, 'A nice big house and nice cars,' and also, 'She earns money, she can look after herself, she pays for her own kids, she doesn't want any money from you at all...'
"F*** yeah, I'm interested in her now."
