Ben Affleck’s exit is official, despite past promises he’d stick around — not only in his wedding vows … but also on the epic engagement ring he gifted Jennifer Lopez.

Back in 2022, J Lo spilled on “The Zane Lowe Show” they were both so head over heels in love on their second go-around that Ben had “not.going.anywhere.” engraved on her engagement ring as a constant reminder of his commitment.

Jen said Ben even signed off his emails with the same message when they reconnected after 2 decades apart … and the phrase meant so much to her she named one of the tracks on her recent album “This Is Me… Now” after it.

Of course, that reassurance was a big deal, especially after their first engagement went south in 2003. But as we know now, their second chance didn’t stand the test of time either.

We broke the story — Lopez finally filed for divorce Tuesday … handling the paperwork herself, without a lawyer, with sources telling us there’s no prenup and they still need to iron out their financial issues.
