Jon Gosselin Tells All On 'Militant' Mom Kate, Claims She 'Mentally Tortured' Son Collin

Jon reveals he was heartbroken after learning Kate had sent their then 11-year-old son Collin away to a child and adolescent behavioral camp in Philadelphia behind his back, where the young boy spent a whopping three years.

The reality star dad claims he later received a letter from the Pennsylvania Department of Human Services (DHS) stating that they had received a report of suspected child abuse involving his son and were investigating.

Collin, who now reportedly suffers from PTSD because of the alleged abuse, was rescued by his dad after the boy's older roommate at the institute somehow smuggled out a devastating letter his son penned in crayon to his dad pleading for help.

Jon's manager at the time vetted the youth and also arranged for him to give a legal affidavit stating what he witnessed.

But Collin wasn't Kate's only victim, claims Jon. Jon reveals how Kate also mentally abused and alienated daughter Hannah while also targeting some of the other children.

"I know my children have suffered abuse and I know one day they're going to tell their own story,' Jon told DailyMail TV. "And sadly enough, I know what PTSD is. It's really upsetting."

According to DHS documents seen by DailyMailTV, multiple allegations of suspected child abuse against Kate were investigated, but the agency ultimately had determined the reports were 'unfounded' due to a lack of evidence.

"I think Kate has really poisoned my children's minds against me," he said. "She's put stuff in their minds about my personality. I never cheated on my wife, I'm not a monster, I love my children more than anything."

"I brought Collin home. He's a great kid. I want the family unit together, I even want to co-parent."

As fans know, Jon agreed to a 10-year gag order as part of the couple's divorce and custody deal in 2009.

Now that the gag order has been lifted, Jon says he wants to "set the record straight."

"There's a lot of stuff I want to dispel, there's a lot of untruths," he said. "I have watched my children suffer and I have not been able to say a word. Kate wanted the gag order because she didn't want me speaking the truth."

"I know everything. I lived it with her and without her. So I know every single thing that has transpired and what has been portrayed to the American public, it's not all true."

He explained Kate's alleged "pattern of abuse."

"I understand trying to teach discipline, but they can't even be kids," he says of Kate, whom he claims ran a military-esque regime, forcing the kids to do chores and tasks beyond what any normal child should endure.

Jon remembers Kate enforcing the strict regime during filming, and the children rarely left the family's house unless cameras were rolling.

"We'd go to the beach to do a shoot and say, 'there's the water, run over there... okay, shoot over, let's go.' Like who does that? That was back in 2009 and that's when I started getting in trouble from the crew and production team, I was like 'no they're not leaving the beach, you can leave,' I was telling the film crews to go away."

"When we did film, we did have good experiences," Jon explains. "But they were short. It was like 'cut, cut, cut. Alright, we got it. Let's go. Let's go on to the next one, onto the next one, onto the next one.'"

"What people don't understand is you only have so many hours and minutes to film that day and you're moving a crew around of 14 people and your kids and all this stuff, so they're not really experiencing the whole thing."

"If they wanted to stay on the beach, it's not happening. If they want to ride the roller coaster 10 more times, it's not happening."

He says being in the public eye under constant scrutiny created other personality issues and that his eight children — Cara, Mady, Aaden, Collin, Joel, Alexis, Hannah and Leah — lack social skills.

"It's going to be difficult because they've been isolated so much and they haven't been taught those life skills," he told DailyMailTV.

"Kate's all controlling, she wants to control every situation,' he said, claiming she's so obsessed with doing everything for the kids that they haven't been taught basic life skills.

Kate still controls the four kids she has at home, Jon claims, adding she forces them to film for her new show against their will.

"They don't want to film. They said they have to film. That's heart breaking," he said. "They have all said they have to film because they feel they need to provide a lifestyle for their mother."

After their marriage crumbled in 2009, John claims Collin and Hannah took the brunt.

"Other than ADHD, which is extremely common, Collin has never been diagnosed with any known medical condition, there's nothing wrong with him," explains Jon. "But Kate sent him away, she couldn't deal with him. He was alone for three and a half years with no parents, all locked up. It was inhumane."

Now, after a long legal battle, Jon managed to get Collin out of the institute and now has full sole physical and legal custody of 15-year-old Collin whom he says, these days, is thriving.

The Gosselin family got their first taste of fame in 2005 when a Discovery channel special ran on them called Surviving Sextuplets and Twins, when the pair's sextuplets were just 17-months-old.

A follow up special a year later was filmed and titled Sextuplets and Twins: One Year Later.

Finally, in 2007 TLC offered the family a full-time reality show, Jon and Kate Plus Eight.
