Weddings?

Me and my fiancé have just started talking wedding ideas. I really want something small due to my confidence etc meaning the ceremony being immediate family and very close Friends and maybe a little party afterwards. I’m not into shit like that I’m very much to myself, I have very low confidence and don’t like being around people too long. However my fiancé likes the idea of a massive wedding with a massive party and every man and his dog there. He’s very out-going and loves shit like that.

His family along is 5 times the size of mine as I only have my mum dad sister brothers and grandma.

I don’t know how to approach this, has anyone got any advice?
