The “Blended” star, who married the art advisor in June 2012 after more than a year of dating, says it took her a while to realise he was the perfect man for her, reports femalefirst.co.uk.
Reminiscing about the beginning of their relationship, Barrymore told InStyle magazine: "I mean, it was never really love at first sight. Will struck a lot of my pragmatic sides.
“He was someone who was always reachable on the phone, someone who was a classy human being, someone who had this incredible blueprint of a family that I don't have. At the same time, what I love about him is that he embodies the power of choice. He chooses to be a good person every day."
While she's now blissfully happy, Barrymore says she and her spouse are very different.
“We've made many compromises and concessions, but when it comes to how we deliver likes and dislikes, we're polar opposites. It's still really hard,” she said.
