Jennifer Aniston Is 'at Peace' After IVF Journey: 'She's in a Great Place,' Says Source

Jennifer Aniston is living a fulfilling life.

A source tells PEOPLE the Golden Globe winner, 53, is "really happy right now" after she recently opened up to Allure about her past infertility struggles and IVF attempts.

"She's always been happy, though," the insider explains. "Her dogs are her kids to her and why she's always had them. Her IVF journey was private and hers, and those close to her knew but never asked."

The source adds: "But she's at peace and is very happy in her life. She's in a great place, and she knows that. Kids or no kids, it didn't change her."

Another insider tells PEOPLE why Aniston decided to share her journey now: "She's 53 now and knows the [children] ship has sailed, so why not?"

Aniston previously told Allure that she "was trying to get pregnant," adding: "It was a challenging road for me, the baby-making road."

"All the years and years and years of speculation… It was really hard," Aniston noted. "I was going through IVF, drinking Chinese teas, you name it. I was throwing everything at it. I would have given anything if someone had said to me, 'Freeze your eggs. Do yourself a favor.' You just don't think it."

The Friends alum also slammed the hurtful assumptions that she chose career over kids after her divorce from Brad Pitt in 2005. "It was absolute lies," said Aniston of the "narrative that I was just selfish... I just cared about my career."

"And God forbid a woman is successful and doesn't have a child," she added. "And the reason my husband left me, why we broke up and ended our marriage, was because I wouldn't give him a kid."

Aniston said she has "zero regrets" about how her IVF journey worked out, explaining: "Here I am today. The ship has sailed. I actually feel a little relief now because there is no more, 'Can I?' I don't have to think about that anymore."
