How can I encourage my fiance to be more actively involved in wedding planning?

Soon to be mommy asked:


I don’t expect him to micromanage every last detail but this is OUR day not MY day and I want him to have equal input. I want him to feel like this is our wedding and not just my wedding. I want it to display our style not my style.
He says he wants to be involved but when I ask him questions or try to bring up planning (which I infrequently do) he always says something like, “I don’t know,” “What do you think,” “Let’s talk about it later,” etc.
