Glamour model Price, 36, announced on Twitter earlier this month that the couple were getting a divorce, days after sharing the news that they were set to become parents again.
She said her marriage was over and accused third husband Kieran Hayler of cheating on her with her best friend Jane Pountney.
Now Hayler has spoken out about his affair with Pountney in a candid interview with the Sun on Sunday.
"Jane said she was falling in love with me and wanted to have children. I said it too because as long as I told her what she wanted to hear, I was getting what I wanted," he said.
Hayler said Price is "an absolute mess", and added that he took some blame.
"What I've done is worse than bad. Kate's done nothing wrong. She's been an amazing wife but I've almost ruined her - she's an absolute mess," he said.
"I am blaming myself a lot and I hate Jane. I feel like she is the one who has done this to the family. She made me do this. She didn't say no. She was meant to be Kate's best friend and she didn't even apologise."
Earlier this week, Price thanked fans for their support during the turmoil in her personal life and dismissed speculation that her marriage split was a publicity stunt.
She had tweeted that she was divorcing Hayler a little over 16 months after they married and days after announcing she was pregnant with her fifth child.
Following the revelation Hayler sent messages on Twitter declaring that he wants to ''repair'' his estranged wife's heart.
''Happy birthday to my beautiful wife @MissKatiePrice. I love you with all my heart forever and always,'' he wrote.
''@MissKatiePrice I will repair your heart and I am looking for the light at the end of the tunnel for our fairy tale ending! Believe in me.''
Price was previously married to singer Peter Andre and Celebrity Big Brother contestant and cage-fighter Alex Reid.
She and Hayler had their first child together, Jett, in August last year.
She has two children, Junior and Princess, from her four-year marriage to Andre and a son, Harvey, from her brief relationship with footballer Dwight Yorke.
