"Gilmore Girls" star Lauren Graham is out on the road, metaphorically, after splitting from longtime love Peter Krause in the summer of 2021. Speaking to People magazine weeks before her book of essays, "Have I Told You This Already? Stories I Don't Want to Forget to Remember," is released, the actress reflected on why she split from her boyfriend of 12 years.

"Fundamental" differences seemed to play the biggest role. 

"I think part of all the positives of having known each other for a really long time were there…And one of the negatives of that is we almost came into a relationship as people in their 40s without asking any of the questions people in their 40s should be asking," she said.  

"We had such a good time together that I didn't maybe ask some fundamental questions about 'What are your values and what do you envision?' and those more grown-up things. And then they just caught up with us."

LAUREN GRAHAM HAS A 'GILMORE GIRLS' CLAUSE IN ALL OF HER CONTRACTS IN CASE SHOW RETURNS

Graham and Krause, who starred as siblings Sarah and Adam Braverman in the show "Parenthood" from 2010 through 2015, kept their relationship predominately out of the spotlight. 

Graham has recently been more forthcoming about her relationship with Krause, which also involved the actor's now 20-year-old son Roman from a prior relationship. 

"I was a contributor in the life of his child, and so we're connected. And yes, I'm in a better place, but it's still just a shame. It's just sad to me," she said.

Writing, she said, has been her saving grace.

"I just was not going to let [the breakup] flatten me…I was like, 'Okay, well, look at all the good stuff I have, and look at all the good times,' and 'I'm going to write this book.' Thank goodness I have these outlets and these stories to tell."

In terms of what she is looking for in a future partner, Graham does have some requirements. "Kindness and a sense of humor. At this point, I'm all about having a good time," she shared.
