"They're taking a break," an insider told "Extra," adding that it may not be permanent.
After meeting with famed Rabbi Shmuley Boteach for regular study sessions and counseling, Gosselin "apparently decided he needed to spend some time on his own," the source told "Extra."
Gosselin, 32, and Glassman, 22, first got close in May when Gosselin stayed with her father, plastic surgeon Lawrence Glassman, who once performed a free tummy tuck for Jon's estranged wife, Kate, in New York. The two claim they didn't become romantically involved until the Gosselins filed for divorce in June.
On Thursday, Glassman told the syndicated television magazine show "The Insider" that the one-time reality TV dad takes out his anger on her. She says he throws "mantrums."
Gosselin, who filed for divorce from wife Kate in June, was part of the TLC show "Jon & Kate Plus Eight," chronicling their struggles raising eight children.
Glassman spoke to "The Insider" in a two-part interview airing Thursday and Friday.
