According to Popeater.com, Aniston knew exactly what was going on in her pals’ relationship, but was hoping they’d get through the tough time.
"Jen has known for some time that the couple was in trouble but hoped and prayed they would be able to work it out," a friend of Jen’s tells the site.
"No one knows how painful divorce is more than Jen and she hopes they don't rush into it without exhausting every possibility to stay together."
The source says Arquette definitely dug his grave with the Howard Stern radio interview though, and the chances Courteney would get back with him after that are slim.
"Telling Howard that they haven't had sex in four months is not the way David is going to win back his wife!" said the source. "What he did on Howard confirmed Cox's biggest complaint about her husband, that he needs to just grow up."
The source added,
"Goodness knows Courteney supported Jen during her breakup with Brad Pitt. Now it's Jens turn to be to supportive. After all, isn't that what a friend is for."
