A source close to the former couple told Us Weekly, "Unfortunately, they just couldn't make the relationship work with their schedules. They really tried, but it just wasn't realistic anymore. They were spending more time apart than together."
Poehler acknowledged that she was in a relationship in her 2014 memoir "Yes Please," but never mentioned Kroll's name. She wrote, "I have a boyfriend who knows how to settle me. He puts his hand on my chest and tells me boring stories. On one of our first nights together, I woke up apologizing for my snoring and he pulled out the two earplugs he had worn to bed so that he could hear what I was saying. It was one of the most romantic gestures I have ever seen."
Amy and Nick dated following her split from husband Will Arnett in September 2012.
