Maybe they were shopping for forget-me-nots.

Separated spouses Courteney Cox, 46, and David Arquette, 37, reunited at a Malibu flower mart on Saturday. (The couple has homes in both Malibu and Beverly Hills.)

Married since 1999, Cox recently told Harper's Bazaar that she asked for the trial separation last year because "when you get older, it's more about compatibility than it is love." See more photos of the two in Malibu.

Citing a need for "peace and stillness," the Cougar Town actress added that she's "kind of all over the place, and I need grounding. I want to be calm. I want to change a lot. It's nothing with David. It's just what I'm searching for."

For now, Cox and Arquette (parents to daughter Coco, 6) are trying to figure out what's best for their relationship.

"If [our marriage] doesn't work out, I will have huge waves of pain about failing in that department," Cox said. "But right now I don't have that because I don't know what the future holds and I guess because I have strong feelings for him."

Arquette -- who spent 28 days at the Betty Ford Center in January -- isn't ready to throw in the towel, either.

"I want her to be happy, and if me even being the best person I can be doesn't make her happy in a partner -- like, who she needs, whatever she's looking for -- that's still to be answered," he told Oprah Winfrey in February.

"I know that I'll be with her for my whole life," he said. "We have an amazing family together and we're really great parents together."
