Nowhere was that more evident than in a tense televised blow-out with his on-off girlfriend Hailey Glassman that erupted during an interview with Entertainment Tonight.
Jon, 32, who's definitely not going to be celebrating Bird Day with his estranged wife Kate Gosselin or their eight kids, had planned on spending it with Glassman's family – despite obvious tension in their relationship.
"I still plan on going to her house on Thanksgiving. It's on my schedule," says Gosselin in the interview with ET's Mary Hart.
"On your schedule? What do you mean, 'On my schedule?' " Glassman asks incredulously. "Uh, let's see, should I go to Hailey's or should I sit in my apartment all alone?"
"Sorry, I used the wrong term," a chastened Gosselin responds. "I plan on going – I made a promise to her family I would go to her house."
"Made a promise? You're not doing my family any favors!" she shoots back. "We know what the right thing to do is. We know what we both need. He needs to do his thing and I need to do my thing. We both know this."
Gosselin later hints that the two have ended their romantic relationship. "At this point I shouldn't be in a relationship right now," he says.
And things really heat up when Glassman brings up the topic of his kids.
"Don't you want to be a more honest person for your children not for me, for your children?" she asks. "Don't you want them to look up to you and say, 'Oh, you're honest.' "
Gosselin's response? He stands up and walks off the set.
