How Kris & Bruce Jenner's Marriage Crumbled: Sexless Nights, Separate Lives & Secret Emails To Exes

Many were shocked when Kris and Bruce Jenner released a statement confirming their separation on Tuesday afternoon -- but not readers of RadarOnline.com!

For more than a year, we have exposed every crack in the couple's 22-year marriage, all leading up to the bombshell announcement.

Signs of trouble were first apparent back in July 2012, when Bruce reportedly caught Kris composing an email to her ex, Todd Waterman.

At the time, the National ENQUIRER claimed the momager was even meeting up with the tall, dark and handsome former soccer star behind Bruce's back.

By December, a family insider confided to RadarOnline.com: "Kris and Bruce are all but over. They have grown apart and their relationship is all about business these days rather than love and romance."

"They've built a brand together, though," the source explained, so they remained determined to "keep up" appearances for the cameras.

Come February, the reality television couple's marriage  was "drama-packed," we reported.

"They don't even sleep in the same room any more," one family insider revealed.

"In my opinion, absolutely everything they do now is for show and basically it is easier and more lucrative for them to stay together than to break up."

Soon after that ripple, 57-year-old Kris was accused once again of cheating on Bruce with her former flame, Waterman.

Still, the couple seemed to be weathering the storm in quiet for several months, until things exploded in June when Khloe Kardashian ripped the lid off Kris and Bruce's chilly relationship.

"In my house there's a man room for Lamar Odom, so I think they took my idea and ran with it... they got another house and Bruce stays there sometimes," she revealed during an appearance on The Tonight Show with Jay Leno.

"I'm not for that, but it's too each their own. I think too much time apart is not a good thing."

Days later, a sensational headline claimed that Bruce, 63, was privately complaining to friends that he and Kris hardly ever had sex any more.

But then in an interview for Time.com, the champion Olympian continued to insist that he and Kris were "as committed as ever."

By the end of the month, however, RadarOnline.com had exposed his lies: In an exclusive report, we revealed that Bruce had moved out of the family mansion in Calabasas.

Soon after, Kris confirmed the bombshell report.

Sources close to the couple insisted it was a trial separation but when Kris refused to go to marriage counseling and Bruce began to complain about how he is portrayed on Keeping Up with the Kardashians, the writing was on the wall.

Indeed, in late July, Bruce's son, Brody, reportedly told friends that he wished Bruce would just divorce Kris -- once and for all.

By September, the marriage was "all but over" -- as we reported -- as Kris removed her wedding ring and Bruce continued to live in Malibu, in what was supposed to be just a summer beach house.

Finally, in early October, Bruce and Kris could no longer hide behind veiled excuses when her sister Karen Houghton revealed the explosive news that the couple had definitively separated.

RadarOnline.com's sources confirmed the story days after Houghton spoke out -- and hours after that report -- Kris and Bruce released their joint statement, revealing what our readers had known for almost 18 months.
