In Jennifer Lopez’s new documentary, The Greatest Love Story Never Told, she and Ben Affleck discuss their relationship—including what went wrong the first time around.

“I think I was angry at you for a long time,” the Marry Me actor tells Affleck when he asks if she’s forgiven him. “But that heartbreak set both of us on a course to figuring ourselves out to being better people. I think I’ve forgiven you all the way. I think I need to forgive myself [for] some things.”

The pair called off their high-profile wedding the day before it was scheduled to take place in September of 2003. They went their separate ways in January of 2004, before getting back together nearly two decades later in the spring of 2021.
