• Jennifer Garner's ex-boyfriend John Miller helped her heal and move on from Ben Affleck
  • Miller was reportedly ready to marry Garner, but she could not commit to him
  • Garner and Bradley Cooper are just friends amid dating rumors following their beach sighting in Malibu

Jennifer Garner's ex-boyfriend John Miller was significant to the actress because he brought her back to life after her divorce from Ben Affleck, according to a source.

Garner and Miller dated in 2018 after her divorce with Affleck was finalized. However, last month, the two called it quits, but they remain friends.

"He made her feel beautiful, confident and sexy," a source told Us Weekly before adding that Miller convinced Garner "that there were men who could be trusted" after her failed marriage with the "Batman v Superman" star.

"He came into her life at a low point and became someone very significant," the source continued.

"Jen says John brought her back to life. It just wasn’t meant to be.”

Meanwhile, a second source told the outlet that Miller was ready to propose to Garner. In fact, when they were together, they had many conversations about marriage. However, the "Miracles from Heaven" star couldn't see herself tying the knot with the burger mogul, and this left him devastated.

"He was ready for marriage and she just couldn’t commit," another insider told Us Weekly. “They parted on very amicable terms." 

Garner and Miller’s split was confirmed shortly after her beach sighting with her close pal Bradley Cooper in Malibu. The sighting sparked rumors that the “Alias” co-stars could be dating. However, sources close to Cooper and Garner insisted that they are just friends. Also, Garner and Miller had been separated for months prior to the beach sighting.

"Jen and John called it quits several months ago. They've remained friends. They just started seeing less and less of each other and finally called it quits," a source told Entertainment Tonight.

"She has nothing negative to say about John; they just seemed to drift apart. She says he was an amazing stepping stone in her life."

Garner is enjoying her time with her kids — Violet, 14, Seraphina, 11, and Samuel, 8. She has been quarantining with them and even shared a hilarious video of her crying after they finished watching the whole series of “The Office.”

Meanwhile, Affleck enjoys his time with his girlfriend Ana De Armas. He has already introduced her to his kids and the two of them sometimes visit his children.
