Hailey Glassman and Jon Gosselin

“That was a huge mistake, because if [Kate] would’ve done that to me, I would have been extremely pissed off. Not because our relationship is over, it’s almost like a stab in the back,” the former Jon & Kate Plus 8 star said. “And now that I think about it, it was a very wrong thing to do. I definitely regret it.”

Jon Gosselin seems to be taking the advice of his new spiritual adviser, Rabbi Shmuley Boteach, in admitting to his mistakes in how he has treated Kate Gosselin and his girlfriend Hailey Glassman.

“I don’t want another failure in my relationships. I don’t want to make the same mistakes I made with Kate, with Hailey. I would just be repeating the pattern over again,” Gosselin said. Regarding Glassman’s statements on The Insider last week calling him “emotionally abusive,” Gosselin said he has to be “accountable for my actions. Maybe she used the wrong terminology, but she’s 22, that’s what she knew. Those are the words and that’s how she felt.”

While Jon Gosselin did not confirm an official break up with Hailey Glassman, he did release a statement to Entertainment Tonight on Sunday saying the two had agreed to take some time off and “focus on each of our individual lives.”

“It is important to me to go back to Pennsylvania and be with my children and get through this divorce and decide what I truly want out of life,” the statement read.

Reality TV dad Jon Gosselin told UsMagazine.com last week he was “carried away by the challenges of fame” and wants to “reconnect with my deeper, more spiritual, more altruistic self.” As part of his spiritual revamp, Gosselin – who is half Jewish – has been consulting with Rabbi Shmuley Boteach. As part of his spiritual counseling, Gosselin agreed to speak at a forum at New York’s West Side Synagogue on Sunday. “I wish for the public to know my regret at having, at times, betrayed the moral principles that have always guided me,” Gosselin said.

In addition to study sessions and counseling, Rabbi Boteach also wants Jon Gosselin to break up with girlfriend Hailey Glassman. “I have advised him to end it with Hailey,” Shmuley told the New York Post. “It is unacceptable to be in a relationship with he is still married and has to take care of kids who are hurting. It is not a healthy relationship.”  Rumor has it Gosselin may use the forum to publicly acknowledge his split from Glassman.

As for Hailey Glassman, she took to her Twitter feed to thank those who have supported her decision to speak bluntly about her relationship with Jon Gosselin on The Insider. “I just want to thank everyone for their support,” Glassman Tweeted. “I was brutally honest and put everything out on the table infront [sic] of the entire world.”
