Have your fiancé do the things that will interest him most.
There are some guys who like to use their hands, so ask these guys if they’d like to tackle some of the DIY projects like assembling the invitations, putting together the centerpieces or making the favors. Then there are the techie guys who might like to take care of hiring the photographer, videographer or DJ. Let’s not forget the foodies who would enjoy tasting and selecting menu and drink items and might even be up to making some edible favors.  Take advantage of his strengths and skills like being a good negotiator or being technologically inclined to ensure his involvement.

Have your fiancé make the final selections with you.
Rather than getting your fiancé involved in every last detail (unless you want to, of course), it may be easier for you to do most of the research and legwork on a vendor or particular idea and narrow down the choices to a few. You can then present say, your top three picks to him, for the final selection.  Having photos of the top choices may also help your fiancé make his decision.

Make him a task list with deadlines.
If you find you need to split the tasks equally between the two of you, make a list of the tasks you and your fiancé would be able to take on with a due date. This helps to keep you both on task without stressing.  It also enables you both to check in and update each other on the progresses made, creating a balance of tasks and good communication.

Some men want to be involved in all aspects of wedding planning while others have little or no desire to get involved, but no matter what type of fiancé you have, do make an effort to include him as it’s his special day too.
