The 32-year-old father of eight fought with Glassman, 22, during a joint interview with Entertainment Tonight, and then stormed off the set.
"We're going to take a break and decide," Gosselin said to ET's Mary Hart. "We'll let Hailey decide on what she wants to do. ... My life is so hectic right now I have to concentrate on my own decisions. ... Maybe she wants to go get a job. Maybe she wants to date other people. Maybe she wants to experience life. Live on her own and do her own things. I don't know. If I was 22, I would probably want a break too, because it is so much."
"It's hard, because when I do [try to leave], he cries," said Glassman. "As hard as it is for us, he needs to go handle his stuff, be with his family and handle his divorce, and I need to go and be a 22-year-old and get my life back."
The interview became heated when Glassman said she didn't "want to do this on national TV." Gosselin was quick to reply, saying he wanted to discuss it in private, but "now it's public."
"This whole thing's uncomfortable," Gosselin said. "I don't like it. I mean, you're telling me out there that you love me and you want to be with me, and then you..."
"I do love you, and you tell me you love me — we would love each other and we want to be with each other, but it's not healthy!" Hailey responds.
"I'm not talking anymore," said Jon.
Things quickly went from bad to worse when Glassman brought up Gosselin's kids and asked him if he wanted to be "a more honest person" for his children. "I'm not talking about this," Gosselin said before storming off the set.
