An insider told a news outlet that the Jason Bourne lead always felt bad about Ben Affleck and Jennifer Lopez's relationship.
"Matt tried to warn Ben when he got back together with JLo that this could happen," the source spilled. "Matt was there to help Ben get it together after their first split and he felt like this would happen again."
The dad-of-three, aged 51, and JLo, aged 54, first started dating in the early 2000s. However, they called off their engagement and married other people. In 2021, they got back together and tied the knot the following year.
OK! reported, that a separate source claimed Damon "hates the way JLo treats" her Affleck.
"Seeing his pal out there posing on one red carpet after another, totally playing up this role as JLo's arm candy, makes Matt nauseous," the insider revealed. "He can't stand to see her emasculate Ben."
