"I don't really make a lot of [wedding] decisions," the Chicago Bears quarterback, 28, said Wednesday on the Windy City's Waddle & Silvy ESPN radio show.
"I hear about them in passing or if I have to possibly write a check or something like that, but other than that, whatever she wants to do, I'm on board."
Joking that he's "just kind of along for the ride," Cutler – whose former Hills star bride-to-be, 24, Tweeted about the re-engagement on Wednesday – told the show's hosts that they are "asking the wrong person" when it comes to knowing about the date or location of the impending nuptials.
Although Cutler isn't devoted to helping plan his big day, a source tells PEOPLE he does seem committed to making this relationship work the second time around.
"Things have been going really well," says a Cavallari pal of the duo, who initially broke off their engagement in July. "They're happy together. They just now understand each other a lot better. He understands what she needs and she totally supports him. They're there for each other."
