After Jennifer Lopez officially filed for divorce from Ben Affleck, rumors circulated for months indicating that their marriage was on the rocks, but sources continue to provide alleged insight into what caused their relationship to fail.

According to a friend of Lopez's who spoke exclusively to Page Six, the “great love Jennifer believes in” is “not in [Affleck's] DNA.”

“Ben has a darkness that others can't fix,” the source told the magazine. 'Jen Garner [Affleck's ex-wife] couldn't fix it, and no amount of success in the world could fix it.'

The source went on to say that Lopez gave “everything she had” to the marriage, but sadly, to no avail.

“She would have done anything to make this work,” the source continued. She opened herself up to criticism, ridicule, and countless naysayers who told her that this was a bad idea, that it was hopeless, that there was a reason it didn't work the first time. But she refused to believe it.

Lopez filed papers to end her marriage to Affleck on Tuesday, August 20, which coincidentally (or perhaps not) coincided with the soon-to-be former couple's second wedding anniversary. [...] [...] [...] [...] [...] [...] [...] [...] [...] [...] [...] [...]
