Sources agree the couple married too young & it was only a matter of time before they called it quits. What do YOU think?

Ashlee Simpson, 26, and Pete Wentz, 31, weren’t even married for three years before Ashlee filed for divorce last week — and it sounds like they spent their whole marriage drifting further and further apart!¬†“They have been talking about splitting up forever,” a source close to the couple tells Us Weekly. adding that Ashlee’s party girl ways drove Pete to stop trusting her.

Ashlee has reportedly been staying out late “for the past few months,” partying with pro-skateboarders and publicly binge drinking at Hollywood hotspots. And while rocker Pete isn’t exactly tame, insiders say he became increasingly embarrassed of his wife’s rowdy behavior.

Another source believes the marriage was doomed from the start: “After she got pregnant, everything changed,” the insider claims. “She had to grow up quickly.”

But at least Ashlee and Pete seem to be keeping up appearances for their 2-year-old son, Bronx. The trio was spotted having lunch Feb. 14 at the Beverly Hills Hotel. And even though it wasn’t necessarily a happy scene, at least they were all together.
