Jennifer Lopez is “upset and disappointed with” Ben Affleck amid their divorce, according to a source.

Lopez, 55, filed for divorce from Affleck, 52, on Aug. 20, listing a separation date of April 26, the two-year anniversary of their Georgia wedding. The pair has spent most of the summer apart amid speculation about their relationship.

“It’s really hit her hard,” a source tells PEOPLE of the Atlas star. “She’s very upset and disappointed with Ben.”

The insider adds that Lopez isn’t comfortable living in the Beverly Hills mansion the two purchased in May 2023 for a reported $60 million. “She and Ben bought the house for the whole family. It’s way too big for her and filled with too many memories as well,” says the source.

Lopez and Affleck’s blended family includes his children with ex Jennifer Garner — Violet, 18, Seraphina 15, and Samuel, 12 — and Lopez’s kids with ex Marc Anthony — twins Max and Emme, 16.

The actress-singer filed her divorce paperwork in Los Angeles County Superior Court without an attorney present. The move suggests she “just wanted to get this done” and move forward, a legal expert told PEOPLE on Aug. 21.

Another source told PEOPLE earlier this week that Lopez is “doing as well as she can” and “seems relieved” after filing. “She didn’t want a divorce. She wanted to figure things out.”

On Sunday, Aug. 25, Affleck was seen out to dinner with friend and collaborator Matt Damon and Damon’s wife Luciana at the Los Angeles restaurant Toscana. A source told PEOPLE that the Oscar-winning filmmaker is “doing well and is very focused” in the wake of the filing.
