I've been dating my Jewish boyfriend for 8 months now and have been engaged 5 months?

and we are planning to get married in two weeks and he is the most amazing person, and he is brought up Jewish and i am also Jewish as well, and everything is perfect with us, but i;m just afraid in our culture we do a lot of prenups and to me that is a deal breaker and i won't sign it and i get a feeling he may, what should i do or say without offending him, i just personally won't sign it and think it says i could be a gold digger which im not, any good advice i really don't want to call off and break up. were so great together.
