The 'Mad Men' star, who recently sought treatment in rehab for alcohol abuse, said he does not make any decisions without consulting the 45-year-old actress, reported Contactmusic.
"Well, Jen and I have been together for 17 years now, and everything that happens in our lives gets run by one or the other," he said.
The 44-year-old heartthrob also credits his long-term partner for helping him to detach himself from his character Don Draper after recently wrapping up work on the final season of the show.
