Amy Schumer and her estranged husband Chris Fischer's seven-year marriage ended on good terms, a source exclusively confirms to Us Weekly. "Amy still adores Chris, just not romantically," the insider shares. "He's a great guy and an even better father." Schumer, 44, announced her separation from Fischer, 45, in a since-deleted Instagram post on December 12 after weeks of speculation about their relationship status. "Blah blah blah Chris and I have made the difficult decision to end our marriage after 7 years," she captioned a throwback photo of the couple on a New York City Subway train. "We love each other very much and will continue to focus on raising our son. We would appreciate people respecting our privacy at this time." Amy Schumer and Chris Fischer's Complete Relationship Timeline Schumer added, "Amicable and all love and respect! Family forever." The source explains to Us that the pair's marriage simply "lost its spark," which led them to go their separate ways. "There wasn't some big, scandalous catalyst for their split," the insider says. "It just happened slowly over time, and they agreed their relationship was no longer what it once was." The source reveals that Schumer and Fischer's separation "has been months in the making because they've been figuring out how it will look," particularly for their 6-year-old son, Gene. (The estranged couple already sold their Brooklyn townhouse for $11 million in November.) Amy Schumer's Transformation Through the Years: Motherhood and More "The goal is to make it as smooth of a transition as possible so as not to disturb their son's day-to-day," the insider tells Us. "One of the many things they see eye to eye on is Gene and his happiness coming first." Despite the major life change, the source shares that Schumer - who recently revealed her 50-pound weight loss - is "in a good place and even cracks jokes about their separation," which has "been an easy adjustment so far." Us Weekly has reached out to Schumer's rep for comment. Schumer and Fischer, a chef and James Beard Award-winning cookbook author, were first spotted together in November 2017. Just three months later, Us broke the news of their secret Malibu wedding, which Jennifer Aniston, Jennifer Lawrence, Larry David, Jake Gyllenhaal, David Spade and more celebrities attended. Amy Schumer's Celebrity Friends Give Their Support Following Her Split "Most of the guests found out the wedding was happening on Tuesday from a text message sent out by Amy on Sunday," an insider told Us at the time. "It was like, 'Hey, this is happening. If you can make it, great. If not, no worries.' People were in and out all night. It was a gorgeous day." In October 2018, Schumer revealed she was pregnant with her and Fischer's first baby. She gave birth to Gene the following May. "I didn't know I could love someone that much - no offense to my husband," she told Entertainment Tonight in November 2019 of becoming a mother. "I think we're both shocked by the level of love that's possible."
