I dunno- suppose after you were married your rabbi said something that offended her so much she couldn’t ask him shailos–what would you do then? Just say “I’m in charge of halacha and I say you will listen to him?” Thay doesn’t sound like a very good family dynamic.
Talk to her. Figure out what her concern is. Then come to a solution that both of you can accept. Think of this as an apportunity to see if you are both ready to be married to each other. If you can’t figure this one out, chances are you won’t be able to figure out what school to send your kids to either.
