<human>: My fiancé of three months is being a nightmare about wedding planning. We're east coast based.

He's a huge Game of Thrones fan...which is fine. I like the show but I'm not obsessed. He's done the following things:

*showed me pictures of Ciara's wedding dress and said I should 
wear the same thing because of how it looks like something that would be in a modern game of thrones wedding.

* wants to call our reception a "feast"

* wants me to wear my hair similarly to the main villainess on the wedding day

*wants a cloaking ceremony during our wedding ceremony

*wants us to rent a mansion that looks like a castle that we can't afford for the day of.

I want a traditional ceremony and reception. The looks he's showing me are not what I want to wear or look like on my wedding day. When I tell him that he sulks and pouts and accuses me of not taking what he wants into account. Call me crazy, but I'm not sure how I can work a cloaking ceremony into a Catholic wedding service. He insists we should ask the priest anyway.
We work at a very large company. We are planning to invite some of our peers, some of whom are upper management. I really don't want to feel embarrassed on my wedding day. Is there a way to compromise?

Summarize the given text in a few sentences.
<bot>: Fiancé wants a game of thrones wedding, I do not. How to compromise without looking like complete dorks.
