Tori Roloff says she's "Exhausted, Sleep Elsewhere!!!" - Little People, Big World

In Tori Roloff and her husband, Zach, a huge marital problem appeared on the horizon.
But, unfortunately, things aren't going smoothly between them.
"You don't yell that much," Zach begins to say, but Tori angrily interrupts him and corrects him as follows:

"I don't yell ever."

I don't understand what prompted this altercation.

Then Zach rocks back in his chair and somewhat smugly replies, "oh, I wouldn't say ever," a remark that doesn't put his wife's mind at ease.
