Jennifer Aniston’s friends upset about John Mayer’s unofficial press conferences

.

“Jen will never kiss and tell, but it’s she who ended the relationship,” a source close to Jen says. “(Mayer's) childish behavior only confirms she was right to dump him. Now he’s acting like a spoiled child. Expect Jen to behave like a lady.”

"I ended a relationship to be alone, because I don't want to waste somebody's time if something's not right,” Mayer says.

Yet Aniston's pal says the something that "wasn’t right" was Mayer’s behavior toward the press during the relationship. “He has a relationship with certain paparazzi (and) bloggers," the source said. “He tips them off. He loves the attention. Jen didn’t want to believe it was happening, but it was, and she has no tolerance for that.”

Another issue: Money. “Jen was tired of paying for everything," said another source close to Aniston. “Cobwebs come flying out of (Mayer's) wallet when he opens it. John liked living like a movie star when he was with her. ... Jen would never say anything, but you could tell it irritated her.”
