I would just tell him that you don't want to be "the boss" in the relationship and you'd rather him make most of the decisions unless it's something you-all just really NEED to talk about and decide together. And tell him you're old-fashioned in that you like for the man to be the decision-maker. You just don't want that job. You want to be the woman and you want him to be the man that takes charge and handles things.
Am I to understand you don't like being in control? You want him to have control? Well, if u are sure, just say , 'yes dear', 'anything you say dear'. 'What ever you want dear', but with those words it creates disrespect and may lead to abuse. Why not be his equal??
