I think each partner in a marriage wants to be valued and have a voice.
In an earlier post in this thread, you gave an example of an exchange regarding going out, and how you handled it "before" with a back and forth .."what do you wanna do?", "I don't know, what do you wanna do?" exchange. From that you moved on to learning a more decisive exchange. And as long as you can keep that decisive exchange going without totally ignoring or stampeding over your wife, you'll be fine. As long as you value her input and allow her a voice, you'll be fine.
The following would be an example of a decisive exchange gone too far:
H: I've decided we should go out to dinner at <restaurant> tonite at 7. Be ready to leave by 6:30.
W: I've had a long, tiring day today. Can we get something to bring in instead and watch a movie at home while eating?
H: No, we're going out. Be ready at 6:30.
In that exchange the H didn't allow the W to have any voice at all and tried to steamroll her. That would be going too far in my opinion as it didn't allow the W any voice in the exchange, and devalued her mental/physical state after a long day - all over a dinner.
So, you don't sound like the kind of guy who is going to go over the deep end and try to control and monopolise or manipulate your wife. If you were, I don't think you would post here with concern about this topic.
So, as long as you keep in mind when you take a decisive action that you allow your wife a voice and you continue to value her, then I think you'll be fine.
