I mostly involved my groom in the things he is interested in...food, cake, tux choices, wording of his family's names. But there were a few times when I was just tired of having to make all the decisions, so I told him I wanted his input because I just couldn't figure it out. He was great about all of this stuff and even handled some tasks I delegated to him like getting the car arranged and sending out an Evite for our pub crawl we did in lieu of a Bachelor/Bachelorette party. My guy knows what he likes so I was careful to ask him if he wanted to be involved in some things that I was unsure of rather than just assuming he did or didn't want to be involved.
