The Jim Halpert actor stopped by Today to discuss the approaching end of The Office as well as to say he is eternally grateful to have been hired on the series.
"It's a little bit of an existential crisis after a while, because I wouldn't have met my wife, I wouldn't have been out in LA," he explained.
The star continued: "Truly, when I say the show has given me everything, it's given me everything."
Blunt met and began dating Krasinski in 2008, with the couple marrying in Italy in front of George Clooney, Jimmy Kimmel and Meryl Streep two years later.
Krasinski recently spoke about how emotional the end of The Office will be and admitted that the cast get to end the series on their own terms.
"We have a really rare opportunity," he commented. "We are not only bringing an end to a show that's been going for a long time, but bringing an end to a show that's been filmed by a fake documentary crew."
The Office airs Thursdays at 9/8c on NBC.
