How to not be a Witch

We had another family trip this weekend for an out-of-town wedding.

I have been struggling with how to deal with lame Beta behavior. 

"How much money should I get at the ATM?"
"When should we leave?"
"Should we go down and look at the lake?"
"What should we do today?"

These questions annoy me.  I feel that the person whose job it is to lead and protect me should be able to make these decisions on his own.  I think I would be much more happy following his agenda than setting the agenda.  Ultimately, these questions have no "correct" answer and I resent being asked to set the agenda.

So, how should I respond?  For the last month or so, I have responded with a blank look.  Sometimes I point out that I think he should be making these calls on his own.  He protests that he is just asking my opinion, but if I give my opinion in any way, the result is the same as if I had lain (laid?) down the law or demanded my way. 

I worry that this refusing to give an opinion in any way is simply another way of being a hateful Witch.  (Sorry, I can't type that other, more offensive, word.  It would make my typing fingers dirty.  I have yet to grasp the art of cursing in print or by mouth.)

How would you handle this situation?  Am I just being hateful and difficult?  In acting this way, am I not attempting to lead my husband?  Yuck.  If that is the case, we are right back where we started.

If you are a wife, how would you handle this?  If you are a husband, how would you suggest a wife handle these situations?

Thanks in advance for your opinion.  Be honest.  Truth is always the best.
