Relationship advice?

i have a fiance who can be a real jerk when it comes to having things his way. we are supposed to take a vacation together this summer..tickets are bought, etc. but he only cares about what he wants, and doesn't even think to ask me about my opinion. i don't want to blow it out of proportion, but i feel like if i don't put up a fight, he will walk all over me. as it is, i feel like i am too nice. today, i hung up on him when he called me a stupid snob because i didn't want to do the things that he wanted to do. i then went to the movies, and came back to find 43 missed calls and 4 text messages on my phone. i know he is sorry, but i just think it's wrong to say things like that to the person that you are going to marry. and i may be a snob, but i don't need that kind of condescending attitude every time i disagree with him. i was crying when i got off the phone, and he knew that. yet, he waited for at least 30 minutes before he chose to do anything about it. it really hurt my feelings.
