i thought my fi would be like yours, shooting down all my ideas but luckily his parents planted in his brains that "it's Danielle wedding. Make sure you let her do what she wants, she's the bride so its really her wedding." Gotta love them for that one.
If i were you i would stop looking for awhile, don't stress yourself out. Tell fi to start looking and see if he picks out anything to your liking. I'm sure once he realizes how much work it is to look through all these choices he'll give up and maybe let you have your way.
