why did amy poehler and will arnett break up

Amy Poehler and Will Arnett broke up after nine years of marriage, officially announcing their separation in 2012 and filing for divorce in 2014. The main reasons behind their split were that their romance had "fizzled out" and they felt more like best friends than a couple in love. Both have described the divorce as painful but amicable, emphasizing that there was no malice or infidelity involved. Will Arnett also experienced a relapse into alcohol use around the time of their separation, which coincided with the end of their marriage, but neither has explicitly stated it as the cause. They remain committed to co-parenting their two children and have expressed gratitude for the roles they continue to play in each other's lives.
