Hilaria Baldwin and Alec Baldwin once considered calling it quits.

The former yoga instructor writes in her upcoming memoir, “Manual Not Included,” about a time she was “ready to walk” away from her marriage.

The couple’s “rockiest” period took place before and after their second child, now-9-year-old Rafael, arrived in June 2015, according to The Sun.

At the time, the duo “fought a lot” about how much Alec, 67, worked — including him replying to emails during her labor.

“It really pissed me off, and I didn’t hesitate to tell him so,” Hilaria, 41, tells readers, adding that the actor’s immediate return to work made her feel “disrespected.”

The “fuming” fitness guru recalls, “I was so focused on how I thought things should be, and Alec was so set in his ways. Neither one of us would budge.”

In fact, Hilaria wrote in her book, which comes out Tuesday, that she went as far as to take her wedding “rings off” to show she was “potentially ready to walk.”

The pair, who tied the knot in 2012, ultimately stayed together and went on to welcome five more children — Leonardo, 8, Romeo, 6, Eduardo, 4, María, 4, and Ilaria, 2.

The duo, who are also the parents of daughter Carmen, 11, even renewed their vows in 2017.

“I need reassurance,” Alec explained to AP News ahead of the Hamptons ceremony. “I need to know I still got you there. I need to know you’re not going anywhere.”

His wife noted, “Once you get married, you’re done. But it’s really good to say, ‘Hey, I’m still in this.’”

Hilaria and Alec’s ups and downs are documented on their TLC reality show, “The Baldwins,” which premiered in February.

During a March episode, the “30 Rock” alum made a rare comment about his divorce from ex-wife Kim Basinger, whom he was married to from 1993 to 2002.

Alec told viewers that one of the “most regrettable things” about their contentious split “was how it affected” the former couple’s now-29-year-old daughter, Ireland.

The Emmy winner claimed in March that his family is “already renegotiating their contract” for the series’ second season.
