<human>: Can you give me the gist of the text in a nutshell?

My long-time best friend and I are getting married after four years of engagement (YAY FINALLY) this coming June. We've picked a location, menus, invited people, etc, etc, etc. Througout this process, I've tried to be as helpful as I possibly can, giving feedback, talking about my preferences, etc.

The problem is...I don't really care about the details. I certainly don't care what color the tables are, or what song we have our first dance to. I don't even care about having a ceremony, to be honest, other than the fact that I know how happy it will make her and it will be nice to have pictures and mementos, etc. I'm not a shy guy, I'm actually pretty outgoing, but I don't like having attention drawn to me for things I don't think are stellear acts (I've always hated my birthday parties, my bachelor party will be just going bar hopping, etc.) I think that may be related to my lack of caring about things.

Anyways, I have of course kept my apathy well-hidden by participating as much as possible, but I think she's beginning to see it (me giving in on basically every point is probably a major part of her seeing it). She's called me on it, and I don't want to come out and say I don't care, but ultimately what I really care about is spending the rest of my life with her. We've been living together for three years, and while getting married will be nice, the actual wedding day, while it will definitely be nice, won't really affect our relationship, will it?
<bot>: Am I an asshole for not caring about the details of my wedding? Is my apathy abormal? How do I care about it more?
