"She got swept up in the engagement last Christmas, but then their schedules got crazy and she realized it wasn't the right decision," an insider tells Us of why the House of Cards actress, 48, called it quits with her beau.
This past summer, the source adds, was the breaking point for the actress, who was juggling working on the Netflix hit in Baltimore and then spending weekends in Los Angeles with her and ex-husband Sean Penn's kids Dylan, 23, and Hopper Jack, 21. Meanwhile, Foster, 34, was busy in London with a production of A Streetcar Named Desire.
The couple's 14-year age difference didn't help matters either, another insider adds. "The gap just ended up being too much," a source close to Wright told Us. "Ben was kind of immature. She couldn't deal with him anymore."
Wright first stepped out with her engagement ring from Foster this past January. The now exes met on set of their 2011 film Rampart.
This would have been the third marriage for Wright, who was previously married to Dane Witherspoon and Penn.
