On April 1, news broke that Drew Barrymore and her husband, Will Kopelman, were divorcing after nearly four years. Now, multiple sources confirm to In Touch that while the news stunned many, their split had been years in the making.

“Drew and Will had created this image that they were one big happy family, but it was all a pretense,” a family insider says, revealing that the couple — who are parents to daughters Olive, 3, and Frankie, 23 months — had been living separate lives for more than a year when Drew finally decided to call it quits.

In Touch, on newsstands tomorrow, is reporting that a turning point for Drew came in February 2015, when she turned 40. She took a trip to Hawaii and realized how unhappy she was.

“Inside, she was crying,” a family insider confirms. “She felt like she wasn’t in control of her life anymore.”

Things got worse quickly.

“Drew began contacting her attorneys in the fall of 2015,” the family insider adds. “She tried to keep it together for as long as she could, but their relationship was broken beyond repair.”

“Part of the problem is that Drew and Will are total opposites. He’s very organized and used to keeping a schedule, and Drew is flighty, always late and is truly a wild child at heart. Because she came from a broken family, Drew tried so hard to play the devoted wife role. She desperately wanted that sense of family and stability, and for a while she thought she found that in Will.”

But in 2014, she returned to the big screen with the Adam Sandler dud Blended.

“At that point, she wanted to ramp up her career again and Will didn’t want her to,” says the family insider. “They fought bitterly about it.”

Adds a source close to Drew, “There was no infidelity, nothing dramatic like that. This has been going on for a long time. They’ve been working on their issues. In the end, they feel like, ‘This is a bummer. We tried.’”

The couple remains on good terms.

“They are still living together,” reveals the source close to Drew. “They have places in NYC and in LA. Both are in LA right now, living in the same house.”
