Ben Affleck’s unpredictable mood swings have been revealed as a key factor behind his recent split from Jennifer Lopez. Sources close to the former couple shared insights into the turbulent nature of their relationship, which ended in divorce on August 20, the same day they celebrated their second wedding anniversary.
According to PEOPLE, Affleck, 52, who is known for his Golden Globe-winning performances, struggled with erratic emotional highs and lows that reportedly strained his marriage with the “Let’s Get Loud” singer. The source described how Affleck’s mood swings created a pervasive sense of toxicity in their relationship.
The insider revealed that despite their genuine love for each other, Affleck’s “darkness” and fluctuating behavior became increasingly difficult to manage. “The truth is there was a great deal of love but also unfortunately what became clear were Ben’s erratic mood swings that he couldn’t hide from the press, as much as he tried to,” the source said. Affleck was reportedly seen oscillating between being “incredibly happy and warm” and exposing his “deepest, darkest behavior.”
Despite efforts to work through their issues, the emotional turbulence proved too overwhelming. “They were trying to work through it, but when the mood swings and the big highs and big lows informed a toxicity that was pervasive, no one can help you — you have to help yourself,” the insider added.
Affleck and Lopez first began dating in 2002 after working together on the film “Gigli” and got engaged soon after. However, they split in 2004, just before their planned wedding. Both went on to marry other people—Lopez to Marc Anthony and Affleck to Jennifer Garner—but reunited in 2021. They were married in a Las Vegas ceremony in July 2022.
Their recent split had been anticipated by fans who had noticed ongoing rumors of trouble in their relationship. According to the divorce filings, the couple listed their separation date as April 26, 2024. Adding to the complexity of their separation is the lack of a prenuptial agreement, leaving their assets to be divided in the divorce proceedings.
As the public reflects on the end of this high-profile marriage, it’s clear that while the love between Ben Affleck and Jennifer Lopez was genuine, the challenges they faced ultimately led them to part ways.
