In an interview with The Sunday Times, the actress, who married the television producer last September, said she and Falchuk spend only four nights a week together under the same roof. The rest of the time the "Glee" co-creator lives at his own home.
Paltrow told the publication that her intimacy teacher, Micaela Boehm, said the living arrangement increases "polarity" in their marriage.
"Oh, all my married friends say that the way we live sounds ideal and we shouldn't change a thing," the "Iron Man" star added.
An unconventional relationship isn't anything new for Paltrow, who famously coined the phrase "conscious uncoupling" when she separated from ex-husband Chris Martin in 2014.
Martin even joined in on Paltrow and Falchuk's honeymoon in the Maldives, as did the children the Coldplay frontman shares with the Goop founder: Apple, 15, and Moses, 13. Falchuk's children from a previous marriage, Brody and Isabella, came on the trip as well.
Paltrow told the Times, "Chris is family and Brad and he, they're like, totally friends."
When asked if she thinks she's a good stepmother to Falchuk's kids, Paltrow said, "I have no idea. Sometimes that piece gets complicated when there are two teenage girls. If you're not all drinking the same Kool-Aid, it can be tough. I do think, though, at the end of the day, everyone wants the same thing, which is to feel love and be accepted."
"My stepson, for example, had a rough beginning with it all, but now he and I have our own space together," she continued. "I'm not his mother, he's not my son, but he knows he is very special to me."
When it comes to her own children, however, Paltrow said they are "f--king awesome people".
"Apple is an incredibly self-aware, strong girl; she knows what's right for her and what's not right," she said. "I'm sure we are going to have some pain and heartbreak, as we all do, but I want to honor who they are. I don't want to force myself upon them."
