Talk about Heartbreak Warfare.

Apparently Jennifer Aniston and fiancé Justin Theroux are having relationship issues yet again. Long distance relationships are always tough and seeing how she's on the West coast while he's in the Big Apple, apparently the miles are putting a strain on their upcoming wedding.

A source close to the couple told InTouch magazine that their careers are causing them to spend less time together.

"Jen always used to be the one who was working nonstop on films while Justin was writing and producing," a friend told the magazine. "But now that he's both filming and producing, their dynamic has changed. It's not Justin's fault - he wants to work more again. But it's caused them to drive apart and spend much less time together."

The couple has been engulfed with separation rumors since they announced they were engaged. While some sources claim they could break off the wedding and their relationship sooner than later, Aniston maintains they're fine and just waiting for the right time to tie the know.

"We just want to do it when it's perfect, and we're not rushed, and no one is rushing from a job or rushing to a job... and, you know, we already feel married," the Wanderlust star told The New York Daily News last summer.
