It's been over 10 years since the two split up amid filming their family's TLC reality show at the time, Jon & Kate Plus 8, but time and proximity to one another doesn't seem to have helped their relationship.
In an exclusive interview, Jon tells ET's Kevin Frazier that it's his hope that he can bring his family back together -- but that just hasn't happened yet. At the moment, two of the Gosselin children, Hannah and Collin, live with Jon, while Leah, Joel, Alexis and Aaden live with Kate. Their 19-year-old twins, Mady and Cara, are away at college.
"I wish that all my kids would just be together, hang out together, go to the mall. Just hang out together," Jon says. "Kate and I don’t live that far away from each other but I feel like there is an invisible wall. They should be able to just get together. I have no qualms about it. If they want to go meet each other, go ahead. I feel like it’s more on the other side."
As for if he's in contact with their mother, Jon tells ET, "I don’t hear from Kate. It’s just totally like that person doesn’t exist anymore."
That being said, the 43-year-old father of eight says he's learned a lot from his divorce and multiple legal battles with his ex.
"I just learned a lot of lessons about people. I’ve had great relationships, bad ones. I've had a lot of lessons along the way," he recollects. "Poor financial decisions and good ones. I have grown and am happy where I am now."
"I wouldn’t be where I am if I hadn’t gone through the things I went through. I know a lot about court," Jon adds. "I am a strong advocate for fathers and other single parents. A lot of people ask me for legal advice."
