Jennifer Garner's relationship with longtime boyfriend John Miller is reportedly under strain as Ben Affleck continues to play a significant role in her life post-divorce. According to RadarOnline, Miller has grown increasingly frustrated by the close relationship Garner and Affleck maintain, believing stronger boundaries are needed despite their commitment to co-parenting their three children.
Miller's Discomfort with Garner's Support for Affleck
A source claimed Miller is uncomfortable with the level of support Garner continues to provide Affleck, particularly during difficult periods in the actor's personal life. "He's trying to deal with Ben and Jen's relationship by mostly staying quiet, but it's very hard to do that," the insider reportedly said. Garner and Affleck married in 2005 and welcomed three children together before announcing their separation; their divorce was finalized in 2018.
Garner's Ongoing Support Through Affleck's Struggles
Throughout the years, Garner has continued to support Affleck during several personal challenges, including his struggles with alcohol addiction. Affleck has previously credited his ex-wife with helping him through some of the most difficult periods of his life and has publicly described the end of their marriage as one of his greatest regrets.
