Off the top of my head, I can't think of many decisions Jesus made as leader of his merry band that are recorded in Scripture. A lot of them are "Geez, we're bushed. Let's get out of here and go somewhere no one knows us" or "Hey, let's feed these people."
The better example of "headship" is what Paul outlines in his epistles: mutual submission. Do what your wife needs you to do, serving her wholeheartedly, and let that be your main concern, not whether she's "respecting your headship."
I knew a guy a several years ago who was getting married and said something nice about having that "as a trump card" for when they had a disagreement. I don't recall my exact words, but the gist of it was that merely feeling that you have the right to have your way because you're the Head of the Family reveals that you are not mature enough to warrant getting your way. Your concern as a married man has to be how you can serve your wife's interests and desires, not the proper ways to express your authority as the husband.
