The affair is over. USA has canceled spy drama Covert Affairs after five seasons, TVGuide.com has confirmed.

Unfortunately, this means fans will never know if Annie (Piper Perabo) chose Ryan's (Nic Bishop) marriage proposal or Joan's (Kari Matchett) invitation to join her CIA task force. And executive producer Matt Corman wouldn't confirm what Annie's "got it" comment meant when he and fellow executive producer Chris Ord spoke to TVGuide.com after the fifth season finale, which is now the series finale. "That remains to be seen! It could be anything really," he said.

"We always want to leave the audience satisfied but with questions," Corman explained. "Even when we've done things that have been classified as cliff-hangers, we want the journey to have been a fun one and a worthy one, and one that the audience wants to come back for. We probably have left more questions than we ever have before with this one."

In hindsight, maybe that wasn't the best decision, but in his defense, Covert Affairs' cancellation is a bit of a shocker. USA recently decided to abandon its move into half-hour comedy, so ending one of its longest-running shows is a bit unexpected.

Per Deadline, the rising cost of the show--including talent fees and more expensive locations shoots--coupled with the show's declining ratings, played a role in its demise. Season 5 averaged just 445,000 viewers in the coveted adults 18-49 demo. That's even less than the already canceled Rush (509,000). When time-shifted viewing was taken into account, the show averaged 3.3 million total viewers, but those numbers ultimately weren't enough to save it.

The cancellation is also surprising considering that USA granted White Collar, another one of the network's aging dramas, a shortened farewell season last year.

Both Corman and Ord weighed in on Twitter shortly after the sad news broke on Tuesday.

Without Covert Affairs, USA's drama roster includes Suits, Royal Pains, Graceland, and newcomer Satisfaction. The network also has a few new projectslined up, including Dig, starring Jason Isaacs and Anne Heche, as well as Complications and Mr. Robot.
