Ben Affleck and Jennifer Lopez appear to still have a united front.

Ben Affleck, Jennifer Lopez arrives at the Los Angeles Premiere Of Netflix's "The Mother" at Westwood Regency Village Theater on May 10, 2023 in Los Angeles, California.

A source who knows both the actor-director, 51, and actress-singer, 54, tells PEOPLE that their joint appearance at a recent basketball game for Affleck’s 12-year-old son Samuel bodes well for how they are handling the current difficulties of their relationship.

“It’s a good sign they were at the game together,” the insider says of Affleck and Lopez’s attendance at the event, where Affleck’s ex-wife and Samuel’s mom, Jennifer Garner, was also pictured.

Sources close to the couple’s circle have said it’s still unclear what the future holds for the couple, whose marriage has been under strain.

Three days before the game on June 2, Lopez was pictured with Affleck as they supported his 18-year-old daughter Violet at her high-school graduation ceremony, holding hands. (Affleck and Garner, 52, are also parents to middle child Seraphina, 15.)

Lopez’s attendance at Sunday’s game came two days after Live Nation announced the cancellation of her This Is Me… Live tour because the “Waiting for Tonight” singer is “taking time off to be with her children, family and close friends.”

A source close to Lopez told PEOPLE on Monday, June 3, that she is “devastated” to call off her summer concert series but understands the importance of the extra time to dedicate to herself and her loved ones.

“Life is a lot right now. As sad as she was to cancel the tour, she’s also relieved. She needs to take care of herself,” said the insider.

“The decision was something that her team encouraged,” the source added. “Everyone is supportive of her focusing on family right now.”

Despite the recent strain in their marriage, a source told PEOPLE on Friday, May 31, that Affleck and Lopez “still want to put the kids first,” adding of the couple, “Jennifer and Ben have always been very family-oriented.”

“The graduation was a big deal,” the insider said of Violet’s big academic milestone. “Jennifer wanted to celebrate it.”

Still, the current situation has “been heartbreaking for her,” added the source.

Lopez and Affleck rekindled their early-2000s relationship in 2021, and share a blended family. Aside from being stepmom to Affleck’s three kids with Garner, Lopez shares 16-year-old twins Max and Emme with ex-husband Marc Anthony.
