What Went Wrong in Jennifer Aniston & Justin Theroux’s Marriage

Many are still shocked by Jennifer Aniston and Justin Theroux's separation after two years of marriage, but what happened?

Just weeks before the announcement, Aniston, 49, and Theroux, 46, were spotted on vacation in Cabo San Lucas, a trip that was reportedly a last-ditch effort to save their marriage. A source told Us Weekly, “Jason Bateman's wife convinced Justin to go to Cabo. She has been the mediator in recent months, trying to get Jen and Justin to work through their problems and save their marriage. The Cabo trip was a make-or-break vacation for Jen and Justin. They went away with their friends hoping to have fun and work on it.”

The trip didn't go as they'd hoped, according to the source, who said, “The guys and girls hung out separately in Mexico. It didn't work.”

Justin and Jennifer reportedly didn't see eye-to-eye on where they wanted to live. An insider told the website, “Jen tried the whole living-in-New-York-City thing with Justin, but at heart, she is a California girl. New York City just wasn't ever going to be home for Jen. Encouraging Justin to spend as much time as he wanted in New York City is what doomed the marriage. Jen thought by doing so, spending time without her would make Justin miss her more.”

They were reportedly living apart for the last few months. Another pal said, “She prefers L.A. and he has a fondness for New York, but they knew that about each other from the beginning of their relationship. They do their own thing a lot of the time, but they also do a lot of stuff together.”

Over the weekend, Aniston celebrated her 49th birthday with friends in Malibu, while Theroux was promoting his film “Mute” and attending NYFW shows in the Big Apple.

Aniston and Theroux were together for nearly seven years, after meeting on the set of a movie.
