"Listen, I did the hard part," the Brothers & Sisters star tells PEOPLE. "I'm there as long as she wants me there to make decisions, but I really don't think that she wants me making too many decisions."
And he may be right, though it's not for a lack of effort. "Basically it's been a series of yes or no questions," Annable, 30, said at the Project A.L.S Benefit in Los Angeles Wednesday. "Can we have Chuck Liddell marry us? That was a 'no.' Can we get married on ice? That was a 'no' as well. It's weird how she's shooting down all of my ideas so quickly."

"We definitely have gotten to the point where he's like, 'I proposed. I did it. That's it for me. Now take over,' " says the actress, 24. "So tomorrow I'm going out to find the invitations, I've found my dress, and it's going to be this year."
Is family planning going to be this easy?
"He's ready and I'm ready as well," Yustman says of parenthood. "If it happened, I'd be like, 'Let's go for it!' But I also would like a year or two to travel and to get to know each other as a married couple. I hear that it's so different once you're husband and wife. It's exciting and I want to live in that for a little bit. And then I'll have as many kids as he wants."
Which may turn out to be a tall order. Though Annable may have taken a comfortable back seat to the wedding planning, he has a specific idea of how his future brood should play out.
"I want a little hockey team," he says. "I'm a little bit older than she is ... I'm going grey, I wear cardigans now. It's time, you know, I have the itch."
