The 54-year-old actress dedicated throwback photos and a sweet post to Macy on their 20th wedding anniversary Wednesday.
"You took me home in 1985. You married me in 1997. You give me a thrill every time you walk through the door. Thank you for marrying me 20 years ago today. @williamhmacy," she captioned a series of photobooth shots on Instagram.
Macy returned the love by penning a message to Huffman on Twitter.
"Twenty years ago today I did the best thing I've ever done in my life. I married Felicity Huffman," the 67-year-old actor wrote.
Huffman and Macy dated on and off for over a decade before tying the knot in 1997. Macy shared the secret to their successful marriage and teased their anniversary celebration in an interview with Entertainment Tonight in August.
"Felicity and I talk about it all," the star said. "We read each other's scripts and we love to talk about acting. She insists that we talk. She keeps us talking, which I'm not completely against."
"We've always fantasized about pushing all the furniture back, getting a full dance band and inviting all our pals over and having a dance, an old-fashioned swing dance kind of thing," he added of their plans.
