Khloé Kardashian has alluded to the problems in her marriage to Lamar Odom in the past, but in Sunday's finale of "Keeping Up with the Kardashians," the extent of the issues became clearer.

"As many times as I have protected Lamar or dodged a bullet for him, lately everything is getting more than what I can protect or control," the reality star said after Odom's agent called her, trying to find him, according to Gossip Cop . "I'm getting bombarded with questions, and I don't know what to say."

Reports that the couple's marriage was in trouble became percolating months ago, and then, in August, Odom, 33, was arrested and charged with DUI. He pleaded not guilty. Days later, the former L.A. Lakers star reportedly checked into rehab, but left after a day.

Meanwhile, Kardashian, 29, dropped "Odom" (and "Kardashian") from her Twitter and Instagram bios.

"A lot had been going on the past couple of years, just with me and Lamar, and I made that choice myself to just keep that within my marriage, but lately it's getting bigger than me," she explained on the TV show. "What am I supposed to do? I've done everything."

Kardashian's sister, Kourtney, also noted "weird stuff going on" in the marriage.

"I feel like a connection with him because he's married to my sister," she said, "but I don't know what goes on in that house."
