Shepard, 40, agrees the differences between him and his wife
is what spurred him to consider therapy. "When I met her and her friends, I was suspicious of their unbridled happiness. I thought, 'Something stinks here; they're in a cult.' But slowly I began to see her positive way of looking at the world," the Parenthood
star explains. "She gives people the benefit of the doubt. There were hurdles, things she didn't trust about me, things I didn't trust about her. I just kept going back to, 'This person has the thing I want, and I have to figure out how we can exist peacefully.' So we started [seeing a therapist together] right away."
