A rep for the couple revealed to People magazine that they have "mutually decided to split" after less than two years of marriage. But a source told the mag there were visible signs of tension before the pair even decided to announce their decision.
"The few times Kaley and Ryan were out together recently, the tension was noticeable," the source told the mag. "You could tell the honeymoon phase had ended."
"It seemed they were trying to work out their marriage by going on dates, but they both seemed miserable," the source continued.
The source went on to reveal that the The Big Bang Theory star likes to keep busy while her husband enjoys life at a slower pace.
"Kaley and Ryan seem to have totally different personalities," the source said. "Kaley is extremely focused and high-energy. She seems to always be working. On her off time, she also keeps very busy."
But, "over the summer, Ryan spent a lot of time at home," the source continued. "He has been struggling with injuries and barely practiced tennis. He has acted very down."
This year has been a particularly unlucky year for love in Hollywood, as Cuoco and Sweeting join the long list of other celeb couples who have ended their marriage in 2015.
