The 37-year-old Oscar-winner and Summer were introduced by the model's older brother Joaquin, who starred in the 1995 drama To Die For with Casey. The two were just "flirty friends" at first, Summer told The Telegraph. It wasn't until four years later that the pair actually began dating and then eventually got engaged in 2003. In 2001, the couple brought their love to the stage, performing in the play This Is Our Youth with Matt Damon, another member of the Affleck pair's inner circle.

In 2013, Ben Affleck's little brother reflected on happier times during an interview with The Daily Beast. "She was going out with someone else and I said, 'Man, she's cute,' and [Joaquin] said, 'You should see if she'll go out with you… don't worry about that dude.’ So he was leaving town one day and said, 'My sister's in my apartment and she's all by herself—would you mind checking in on her?' So I checked in on her, and it stuck."
