On Sept. 3, 2021, Cuoco and Cook announced in a joint statement to E! News that they decided to part ways after three years together. "Despite a deep love and respect for one another, we have realized that our current paths have taken us in opposite directions," the former couple stated. "We have both shared so much of our journey publicly so while we would prefer to keep this aspect of our personal life private, we wanted to be forthcoming in our truth together. There is no anger or animosity, quite the contrary."
The duo continued, "We have made this decision together through an immense amount of respect and consideration for one another and request that you do the same in understanding that we will not be sharing any additional details or commenting further."
The couple celebrated their three-year anniversary on June 30, 2021. "2 years to the day before we got married and now 3 years married!" Cuoco shared, before joking, "Why have you stayed married to me for so long?! I'm sincerely impressed @mrtankcook lol"
Cook countered Cuoco in his own anniversary tribute, writing, "I agree @kaleycuoco I am just as amazed it's been been three years, feel like just a flash. I love you so much and I can't wait for a million more years!!
Cook adorably surprised Cuoco ahead of the virtual 2021 Golden Globes. "So most of you know that Karl has been away at WEF [Winter Equestrian Festival], a big equestrian event circuit, for many, many, many, many weeks, and was not going to be able to come to for the Globes tomorrow," Cuoco shared on Feb. 28 with her Instagram followers. "But we had talked about it, and it was okay, because it's virtual and I didn't want to make him come back for that. Well, I just answered the door and...he showed up."
Cuoco then shows Cook on-camera, who waves before saying, "I showed up. I was in the area." Cuoco emotionally hugs Cook, adding, "I can't believe you got me so good," she said. "I can't believe you did that!"
The couple officially moved in together in March 2020, and gave fans a tour of their new digs on Instagram. "First #KarlFasahioned in our new home. I love you so much," Cuoco said with a smile as she cheers'ed to their next chapter and shared a kiss. "New house, rain, movie night, wheat thins, husband cooking, puppy, cocktail," Cuoco wrote in another video. "This staycation is OKKKK."
Cuoco joked during Jimmy Kimmel Live! a month later that living with Cook has "been great for our relationship," before adding, "and we like each other we realized, which is even better."
However, she later quipped on Conan that their living situation was temporary. "He's out. This is just for the quarantine," Cuoco said. "I don't want to give the wrong impression here." Perhaps Cook's mullet had something to do with the ultimatum? Meanwhile, the couple got comfortable kissing through COVID-19 masks!
Cuoco and Cook took the big leap and made plans to move in together in Feb. 2020. A source told E! News that the couple were looking to expand their family as well. "Kaley and Karl talk about having children,"the insider shared ahead of The Big Bang Theory finale. "They would love to move to a simpler lifestyle and live on a ranch with their horses. Kaley wants her children to be raised riding horses and having a similar country lifestyle that both her and Karl love."
Cook wished Cuoco a very happy b-day with a sweet Instagram tribute while Cuoco was filming The Flight Attendant in Bangkok. "Happy birthday @kaleycuoco love of my life!!" Cook captioned in Nov. 2019. "You're the greatest most amazing woman on the planet, minus @lifewithshmooshy of course. I am so excited to live everyday together."
Cuoco gushed during Brad Goreski's Brad Behavior that she has "the best relationship" with husband Cook, despite not living together. "We are so happy and yes, we have separate lives and then our lives come together and he's so supportive of me," The Big Bang star explained in Nov. 2019. "He lets me be me and I let him be him."
Cuoco continued that she did not want to rush into cohabitating with Cook due to her past relationships. "We've kind of been in separate places but as people see, we're together all the time. But we've had separate locations and whether that's helped us mentally or not, I've obviously never been in a better relationship and I want this to last the rest of my life so in a way, we're actually taking it slow," she revealed. "We've been together for almost four years. We've not lived together. We are building our house. We will be under the same roof eventually but this has worked for us."
Cook shared a series of candid pics of Cuoco on Instagram to mark their first wedding anniversary on June 30, 2019. "Everyone posts wedding pictures amongst other idealized images on their anniversary, not me," Cook captioned. "These are images of my gorgeous wife I remember...I love you @kaleycuoco."
Cuoco similarly shared, "Happy one year anniversary to my incredible other half! @mrtankcook I still can't believe you're mine and I'm never letting you go!"
