It doesn’t take a relationship guru to know that if your romance is strained, it’s probably not a good idea to publicly expose its flaws. When Amy Purdy and Derek Hough danced the Rumba on last night’s show, Purdy revealed that it’s difficult to do a “dance of love” when her own long-term relationship is failing.

In fact, these issues have actually been brewing for 1.5 years, which is especially shocking considering her non-marital status. After all, shouldn’t you wait until marriage to be miserable? Watch the video package below, and take special note of how NOT to behave in your relationship, on facebook, and any other public forum. That poor guy.
