Hey, I thought I'd bump this one up, since it has tons of good advice that all new members can use :)
My advice to avoid headaches would be: listen and compromise. You might want something, but your FH might want something else. Don't get set on your idea without considering his, because, ultimately, the day is about the both of you, not just you. Once you have both presented your ideas, you can see how they go well together and still be something you both love.
