why did will arnett and amy poehler divorce

Will Arnett and Amy Poehler divorced because their marriage "fizzled out," with the romance dying over time after nine years together. They reportedly grew more like best friends rather than a couple in love, and neither was happy anymore, which led to an amicable split without scandals or infidelity. They separated in 2012 and finalized their divorce in 2014, sharing joint custody of their two children. Will Arnett has described the period as emotionally brutal and painful, and Amy Poehler has said the divorce "really sucks," though both emphasize maintaining a close friendship and co-parenting relationship. Will also experienced a relapse into alcohol use around the time of their separation, but neither has stated this was the reason for the divorce. Both have been candid about their earlier experiments with substances before they married but suggest their parenting responsibilities changed their lifestyles drastically.
