The Fight Club actor, 61, has been dating his 32-year-old jewellery executive girlfriend since at least 2022 after he and Jolie were declared legally single as of 2019 - before they finally settled their marathon eight-year battle over the terms of their split at the end of December.
A source has told Page Six it was de Ramon who "influenced" Pitt to "settle" with Jolie so their lives could make "progress in the right direction".
"He was influenced by Ines to finally settle. Ines wants to have a life together - with possibly children in the future - without the albatross that was the eight-year War of the Roses," the insider said.
"(De Ramon) has made (it known that) her opinion is that life would be much more enjoyable with this settled."
A separate source told the Mail that de Ramon is a "positive influence" on Pitt as she "has a really good perspective on things".
"It's sad how this whole thing has played out, but at least this is progress in the right direction," they said.
Jolie filed for divorce from Pitt in September 2016 after they were married for only two years.
It was days after they took a now infamous trip on a private jet, during which the acto said Pitt was abusive to her and their six children, though authorities did not charge him after investigating.
Jolie and Pitt released a joint statement declaring they would keep all divorce proceedings private for the sake of their children Maddox, 23, Pax, 21, Zahara, 19, Shiloh, 18, and 16-year-old twins Vivienne and Knox.
Even though the pair have legally been single in 2019 they have been mired in labyrinthine legal battles over the custody of their children and ownership of their French estate and winery Chateau Miraval.
