'Til death do us part? It's been five years since Arnold Schwarzenegger and Maria Shriver split and moved on with their lives. In fact, he has a girlfriend and she has a boyfriend.

Oddly, though, Arnold and Maria are not remotely close to actually being divorced, despite Maria filing in 2011 after 25 years of marriage.

So, what's the hold up? Who knows!

The duo married in 1986 and didn't have a prenup, but according to TMZ, they worked out an agreement about their respective fortunes years ago, splitting up an estimated $400 million.

They also never had any squabbles about custody of their children. Besides that, they're all adults now.

The former couple hasn't really shed any light on why they're still married. There are several theories, one of them stating that neither wants to walk about from the fortune they're amassed together, but that line of thinking doesn't make sense because of their aforementioned agreement.

TMZ says that another theory is that Maria "doesn't believe in divorce" because she's "super religious." Still, Arnold could make things official if he wanted. Apparently he has no interest in pulling the plug on the marriage.

Last October, there was a report that Arnold was the one wanted to maintain the status quo.

"Whenever Maria says she wants to move on with her life, Arnold drags his feet," a source told TMZ.

In 2015, the "Terminator" star blamed himself for the dissolution of his marriage.

"This was without a doubt the biggest setback and the biggest failure [in my life]," he said. "Not only failure, but you really feel like, 'I'm to blame for it. It was me that screwed up,' and you can't point the finger at anyone else."

Five years and counting... And you thought Chris Martin and Gwyneth Paltrow took a long time to officially split!
