“Communication was definitely a challenge between him and Margaret,” a source shared with Page Six in July 2026. They claimed Antonoff was “particular about how he liked things.” Continuing, they added, “He’d often prefer for things to be done the way he thought was best, and Margaret didn’t always feel like her perspective was being heard or given the same weight.”
With that said, People‘s update on the breakup provided a slightly different reason for their split. According to the outlet, Antonoff and Qualley always had issues within their relationship. Specifically, the outlet claimed that they faced a lot of conflict surrounding Antonoff’s busy schedule as a music producer. “They argue a lot, and between her career and him constantly being on the road or working late in the studio, it’s been difficult,” they claimed.
