Since we have established that this day is for the Bride and the guest, we can not forget that there would be no bride or guest without a Groom! The days of grooms not being involved is over for a number of reasons: 1. They want to contribute and have ideas too, 2. They have dreams about their special day too, 3. it is socially acceptable for them to do so and still keep their Manhood in tact. With that being said it is wise to talk about what will be done by whom. This is a great way to see how you guys work as a team (a force). Identify things to be done and by whom. The groom at the very least:

I. Select the Groomsmen
a. Choose their outfits
b. Buy gifts for the men in your wedding party
II. Make your Guest List...groom and bride will put together separate guest lists (before coming together and finalizing the list)
III. Reserve the Wedding Location Don’t hesitate to take the initiative in finding possible sites for the ceremony and/or the reception. (AGREE before the final decision is made)
IV. Plan the Honeymoon Make the bride happy by researching honeymoon destinations
V. Order the Wedding Bands.
VI. Pick the Groom's Cake

And there is so much more that he can do. Even if you have a wedding planner there are tones of things left for the both of you to do together and separately to make this the day that you TWO want and will enjoy!
