How to deal with FH thats just not into the wedding

Hey-
So my FH is so not into the wedding. He is so excited to get married and would do it tomorrow - but just not happy about all the money and the big 'show' as he calls it. He just wants to be married (which is nice)

We've talked alot about it - and since we both have large families there is no such thing as a small wedding. I am pretty much doing all the planning b/c I know he doesn't want to - but then everytime I tell him about something I did - he goes on a tangent about money. (PS - i'm not even telling him the prices)

It really *****!! I am not being an over the top fancy bride and trying to save wherever I can - but everytime I bring the wedding up - he complains, then I get upset.

He hasn't asked any one to be his best men yet either b/c he hates it and thinks they all will too.

How do I deal with this??

THANKS!!!
