Kristen StewartBy now you've all probably heard the news that Kristen Stewart and Robert Pattinson are supposedly broken up FAH REALZ this time -- though they're rumored to still be living together for the sake of their children careers dogs. Details have started to surface about what may have driven the two lovebirds apart. And it ain't pretty.

Perez Hilton reports that Robsten have been "growing apart" ever since Rob got back from New York on May 8. Says a source:

They again went from spending every second together, to spending more time apart at their separate houses. Kristen has been in a terrible mood, and it was obvious that things were not great with Rob. It was very strange that they didn't celebrate Rob's birthday together. He had friends over at his house, but Kristen was not part of the celebration. For the past few days, they have not spent any time together.

Hmmm ... May 8 wasn't THAT long ago. So the couple must have been drifting apart since before that. Like maybe after Rob got back from Australia. The pair were spotted roaming around their Los Angeles neighborhood together after that, but looking none too happy.

Hey, if you want to get really downer about it, things weren't that great or Kristen wouldn't have cheated with her director -- and that was a year ago!

It sounds like they valiantly tried to make it work, but that kind of crack in trust would be difficult to repair, especially for two young people who aren't reliant on each other in the slightest. There's no reason they HAVE to stay together -- maybe they wanted to for love (and the Twilight franchise), but they don't have to for kids or money. Or even their dogs. Dog run playdates!

Additionally, they spend a huge amount of time traveling and apart working on films -- if they were truly committed to working it out, they should have taken a break from all of that. Not easy when you're an actor and you know that you're a couple of bombs from guest starring on Celebrity Rehab.

But given that they've been down this road before, I wouldn't bet that this break is permanent.

Do you think they will get back together? Do you think they're really split up?
