Why Margaret Qualley, Jack Antonoff's marriage ended?

Margaret Qualley and Jack Antonoff's contrasting personalities and outlooks on life ultimately contributed to their separation, according to a new source, following the end of their nearly three-year marriage.

Source says different outlooks created long-term challenges

A source told PEOPLE that Qualley and Antonoff gradually realised they were not the right long-term match despite sharing deep affection for one another.

According to the insider, Qualley has an optimistic and upbeat personality, while Antonoff tends to be more serious, with the pair approaching life in different ways.

The source said those differences eventually became difficult to overcome in their marriage.

Qualley turns attention to acting career

The insider added that Qualley is now focusing on her acting career as she prepares for pre-production on the upcoming horror remake Possession.

According to the source, acting has always been a major part of Qualley's life, and she is happiest when working on new projects.

The actress is said to be looking ahead and concentrating on the next stage of her career following the split.

Couple deny rumours of infidelity

News of the separation emerged shortly after Antonoff attended Taylor Swift and Travis Kelce's wedding without Qualley.

The split prompted speculation about possible trust issues or infidelity, but Qualley's representative firmly denied those claims.

In a statement, the representative said there were no trust issues or infidelity, adding that the pair continue to have deep love and respect for one another.

A separate source also told the publication that Qualley and Antonoff have remained supportive throughout the separation process and are handling it with kindness and unity.
