Aniston - who was previously married to Brad Pitt from 2000-2005 and Justin Theroux from 2015-2017 - told ELLE that having kids isn’t off the cards.
"When they came to an end, it was a choice that was made because we chose to be happy," she said. "And sometimes happiness didn't exist within that arrangement anymore."
"Who knows what the future holds in terms of a child and a partnership - how that child comes in…or doesn't?" she says. "And now with science and miracles, we can do things at different times than we used to be able to."
"We live in a society that messages women: By this age, you should be married; by this age, you should have children," she says. "That's a fairy tale. That's the mould we're slowly trying to break out of."
The Friends star also discusses the public's obsession with her personal life.
"Maybe it has everything to do with what they're lacking in their own life," she said. "Why do we want a happy ending? How about just a happy existence? A happy process? We're all in process constantly."
"What quantifies happiness in someone's life isn't the ideal that was created in the '50s," she added. "It's not like you hear that narrative about any men. That's part of sexism - it's always the woman who's scorned and heartbroken and a spinster. It's never the opposite. The unfortunate thing is, a lot of it comes from women. Maybe those are women who haven't figured out that they have the power, that they have the ability to achieve a sense of inner happiness."
