I'd say tell him how you're feeling. Then you can talk it out and figure out what works best and makes both of you comfortable. He may not have a problem spending a lot on an ering and then getting a very inexpensive wedding band...or maybe if he feels there's no need for and ering especially an expensive one, you can agree on a very fancy wedding band. Either way, at least you will have talked it out with him and you both know where each other is coming from.
