A source close to the couple tells Us their conflicting schedules were to blame. "They really tried, but it just wasn't realistic anymore," the source says. "They were spending more time apart than together."
Poehler and Arnett were married for nine years until they divorced in 2012. They have two sons together, ages 6 and 5. Poehler discussed her relationship with Krohl in her memoir Yes Please, which was released last year.
