Jon Gosselin met yesterday with ex-girlfriend Hailey Glassman to try to work out their differences. “They decided to sit privately at the table and discuss this thing,” her lawyer, Stephanie Ovadia, told The Post’s Kieran Crowley. “They will try to work this thing out.” The re ality-show father of eight claims Glassman ransacked his West 72nd Street apartment and left a note pinned with a kitchen knife. She accuses Gosselin of roughing her up and slamming her against a wall.
