it is precisely the lead aspect of leadership, the decision making and following God's direction to me as the head of the household (even when either woman dislikes it or disagrees) that has gotten me through some of the initial pangs and issues surrounding this, and to the place I am today (where it is a reality and a second marriage is in the planning, not just some theoretical). As @andrew can testify, I've been through a lot of pain to get here, and it's been me saying 'no, sorry, but this is what we're going to do' that has gotten me there.
So perhaps the message in this entire thread is: both 'sides' are right, we just each have different lessons we need to learn and focus on depending on the season we're at in our lives
Amen, @EternalDreamer, we all have lessons to learn in our brokenness.
I'm going to assert, though, that what you're describing in your journey with both of your women is one of leading rather than ruling. Often related issues are incorrectly considered as much more black-and-white than they are. One needn't resort to 'ruling' in order to be in the lead. One of the most powerful strategies that occupies the middle ground between making all the decisions and making none of the decisions (or being led by one's woman) is the power that exists in refraining from making a decision that one's woman wants one to make -- as the one who is 100% responsible for the direction of the marriage, the husband's veto power naturally carries more weight. Decisions don't always just involve choosing among A, B, C and D; they can also involve choosing to refrain from everything from A to Z in a set of circumstances.
A vague example from my current processing with my wife: a great deal of the struggle between us has been alleviated by my simply being unwilling to endorse the myriad of devotions of time, money or other resources required to support the many activities she or our girls regularly propose. When my wife goes through a period of reluctance to address the problems between us, I put agreeing to fund or participate in unnecessary activities on hold as well. The only decision I'm making is to refrain from making a decision or from granting my approval. Sometimes leadership requires standing firm or retreating -- ruling would assert that those under my authority should be required to behave in a way that I determine. I not only see such ruling to be ineffective in the long run but lacking fleshed-out support in the Bible.
My suspicion is that, in the instances you cite in which you say, "No, this is what we're going to do," you have the sense that one or both of your women just want you to make the decision, because, absent some type of physical coercion on your part, there is nothing you could do to force either of them to do whatever it is you're saying you're all going to do unless they have voluntarily granted you the power to make that kind of decision.
Rulers don't have to persuade, because they have the power to force compliance.
