It seems Kaley Cuoco and Ryan Sweeting's marriage wasn't so sweet towards the end. A report claims they weren't getting along towards the end of their marriage and tried to work things out by going on dates. In the end, however, Cuoco and Sweeting decided they were better off apart and announced their divorce last week after 21 months of marriage. 

According to People, the "Big Bang Theory" actress and the professional tennis player would sometimes link up for a date night, but sources claim the "tension was noticeable" and it was clear the "honeymoon phase had ended." 

"It seemed they were trying to work out their marriage by going on dates," the source told the magazine. "But they both seemed miserable." 

Cuoco and Sweeting, who had a whirlwind romance and got married after dating for six months, were plagued with divorce rumors long before they officially ended their marriage. In April, the 29-year-old actress took to Instagram to post a happy photo of herself and Sweeting, writing that the rumors only "made [them] stronger." 

That photo, and all other images of Sweeting, has since been removed from Cuoco's account. Us Weekly reported shortly after the divorce news that the actress erased every photo of her ex from her Facebook and Instagram accounts and also stopped following him on the photo-sharing site. In response, Sweeting disabled his Facebook page and also deleted pictures of Cuoco from his own Instagram account. 

On Sunday, the actress was spotted without her wedding ring on as she walked her dog in Thousand Oaks, California. She also spent Saturday getting her mind off the divorce news by competing at Flintridge Riding Club in La Cañada Flintridge, California.
