Jon Gosselin says his relationship with his eight children has suffered greatly over the past few years in the wake of his divorce from Kate Gosselin.

The former Jon & Kate Plus 8 star tells ET's Jennifer Peros he now only gets to see a few of his kids every other weekend.

Jon and Kate went through a very public divorce in 2009 that left Kate with primary custody of their 15-year-old twins, Cara and Madelyn, and 12-year-old sextuplets, Alexis, Hannah, Aaden, Collin, Leah and Joel. All eight children live with Kate in Pennsylvania.

"Everybody used to come to my house," Jon explains. "You know, it was great, and then Madelyn and Cara just stopped coming, around 12-13 [years old]. I didn't question it. I was just like, 'Hey, do what you want, be with your friends' and then it just became they're not coming."

"Then I had six [kids]," he says. "I was just focusing on the ones that did come and then a couple years went by and then Collin stopped coming. I thought, maybe he just wants to do stuff with Mommy or whatever, and then it became long term."

"I haven't seen all eight of my kids together probably in three years. Three to four years," Jon claims, adding that he hasn’t seen Collin in two years. "The kids that I do get are Hannah, Leah, Joel and Aaden. I guess the four have stuck together and said, ‘We're going to Daddy's and that's it.’ And maybe they'll raise a stink about it or something like that. Sometimes I get Alexis but not often. Madelyn and Cara, I don't see that much, or often. We're kind of not talking right now."

The 39-year-old also claims that, since the divorce, he doesn’t have a relationship with Kate, 41.

"I don't really talk to my ex-wife, so it's all kind of helter-skelter," he says. "I have my life and she has her life. We have our life with our kids separately. We don't go anywhere together."

Kate, who is currently filming, Kate Plus 8 for TLC, has appeared on other reality TV shows including, Dancing with the Stars and Celebrity Apprentice. As far as her love life, last year ET confirmed that Kate was no longer dating 52-year-old millionaire Jeff Prescott.

Jon, on the other hand, has stayed away from reality TV. He recently made headlines after taking a part-time job at TGI Friday's. But, his new gig only lasted for about a month after a photo of him working in the kitchen was leaked online.

Since leaving the reality TV world, Jon has faced endless scrutiny over his career choices. He’s now a resident DJ at the Building 24 night club in Wyomissing, Pennsylvania.

"You know, I kind of walked away from everything so that my kids can have a life," he shares. "So that they would be taken care of, in their house, and things wouldn't change, because I knew I could survive."

Ultimately, he says, he would love more than anything to develop stronger relationships with his kids, especially Madelyn and Cara.

"They're moving into womanhood," he notes. "They'll be 16 in October. I hope I can talk to them and develop a relationship in the future. But there's a lot of stuff that has to go on before that."

ET has reached out to Kate for comment.
