It is her wedding.
You think any different, you are wrong.
The wedding is for her.
The reception is for friends and family and the honeymoon is for the couple.
Some time later, you realize you were just there to facilitate all of it.
I got married so I could go to Disney World.
It turns out you don't have to go there just for a honeymoon.
You can also take her back there when she is knocked up.
