"My mom and my brothers, they say to me, 'It's so good to have the real Jon back. It's so good to have the warm, loving, kind, caring person that we knew you when you were ... before you got married,'" Gosselin said. "I've changed for her. Because I loved her ... But don't forget who you are. That's what happened to me."

Jon Minus Kate

The former reality TV duo now lives the life of parents with shared custody. Gosselin commutes from New York City to the family's Pennsylvania home when it's his turn to be with the kids.

Their ongoing custody battle has resulted in the police being called to their Pennsylvania home, when Kate came home to find the kids with a new babysitter, hired by Gosselin.

"I wouldn't let her in the gate," Gosselin told paparazzi. "I said, I'm spending time with my kids ... and she's going to have to leave, and she tried to cry it up with the cops, and it didn't work and they just basically said [to her], You have to leave."

Despite the drama, Gosselin says he tried everything to avoid reaching this point, including therapy sessions, which proved fruitless.

"I went to therapy. I learned about myself. If she's not going to therapy, she's not going to fix herself, then it's not going to work. It takes two people," Gosselin said. "I have a $22,000 therapy bill. I mean, I tried to have marriage counseling. I did it myself. She refused to go."

Gosselin said that Kate did agree to attend therapy with Dr. Phil, urging Gosselin to fly to California to meet with the celebrity therapist before a scheduled trip to Utah. But according to Gosselin, their session was more about fixing the image of the show than fixing their marriage.

"We talked about the brand and ... and corporate things and making the brand work," he told Cuomo. "I felt it was weird. I was like, 'why am I here? I could be snow-boarding.' I mean, it wasn't helping."

In a statement to ABC News, Dr. Phil said: "I respect the Gosselins' privacy. I have no comment on their marriage."

Reflecting on his failed marriage, Gosselin says he's had his share of doubts.

"I felt maybe I was too passive. Maybe I didn't stand my grounds 10 years ago -- even to stick up for my kids. But it's gone. I can't get that back," he said.
