Chastened by his girlfriend earlier this week, Jon Gosselin is owning up to his mistakes (while receiving a paycheck, of course) and apologizing to Hailey Glassman.

The reality star is trying to make amends with Hailey, who called him an emotionally abusive liar and kind of a d!ck the other night, telling The Insider she's right.

"My girlfriend, Hailey Glassman, has paid a significant price to live under such a media microscope,” Gosselin told the show, which also reported her complaints.

"I am grateful for her emotional support and regret any pain my actions caused as she has selflessly born the pressures I have endured under the media glare."

"I am committed to making things right with Hailey as well as Kate and especially my children. I ask you to please give me the opportunity to prove myself."

When Jon isn't trading public barbs with his new play thing, he's busy tangling with estranged wife Kate over their eight kids, their show and financial issues.

Hard to say which is worse. Okay, no it's not. Hailey actually seems pretty cool and understanding, calling him out but not ditching him either. Kate? Yech.
