According to a source, "Jon is in New York and is speaking to Hailey. They're trying to come to a resolution."
Things have gotten ugly between the pair in recent weeks. On Wednesday morning, reports emerged that Glassman had filed a formal complaint with the NYPD alleging Gosselin pushed her during a Dec. 20 argument.
For his part, Gosselin has insinuated that Glassman may be connected to the alleged holiday ransacking of their apartment.
Gosselin's lawyer also spoke out and attempted to discredit Glassman's claims of pushing, telling RadarOnline, "When Hailey was contacted by police [about trashing the apartment], her legal people decide to come up with this ploy to say he harassed her."
Meanwhile, Glassman's camp is defending her allegations. "Yes, that incident took place on the night of December 20th and there is no denying the fact that my client is in fact a victim of domestic violence," says her attorney Anand Ahuja.
Now, a source tells PEOPLE that the prickly couple are trying to settle their differences privately. "[Jon] won't press charges if she returns what he says is his, like the TV, the Wii, etc."
Glassman's camp has maintained that she had permission to take items from the apartment.
