It never was an actual episode that existed.

Back when Season 3 had yet to air, a behind-the-scenes video of an interview with Ben was released. We discovered a really grainy view of Season 3 episode titles on the whiteboard in the background. Based on that image, we went ahead and made articles. Some of these turned to be wrong (either mis-titled or never had actually existed in the first place.)

Ergo, "The Wife" was nothing more than speculation.
