Oh, that sounds fun!
Here are some of my thoughts. Man of the house is the man that lives in the house in the parental role:-) Woman of the house is the woman in the parental role too. If there is no man, then the oldest boy becomes the man of the house...but I don't really know what that means then. :-)
Are you guys Christian, by chance? This probably spreads to other religions, but I've noticed a lot of Christian men, the ones who tend to be more traditional, they have a view that being the "man of the house" makes them be in charge and the boss and that the woman is submissive to him. I watched some documentary on it once. The husband told the wife what to do and she felt like it was her duty to do whatever he said. He didn't help clean, didn't help with the house, didn't help do any of that stuff. He bossed her around, and she was expected to jump and okay. What he said went and that's how it was.
Just in case I'm offending any Christians, I should add that I am Christian too. We live in a fairly traditional family in that my hubby works and I stay home and raise the kids. We choose to do it this way because it's important to both of us.
NOW...back to you, maybe you aren't Christians, but if you are, then here's my take on it (and, if you aren't Christian, then this might not be very helpful). Somewhere it says that men are leaders of their families. So, I do believe that men should lead their homes. But there are a ton of different types of leaders. There are dominating, controlling, bossy leaders, as well as more gentle, kind, caring ones.
Doesn't Christ also say for us to follow Him? What type of leader was/is Christ? He's caring, compassionate, loving, considerate. He spent his time SERVING others. Christ is the best leader there is. If a man is the "man of the house" based off of Christian teaching, then he better be leading his house as Christ led (leads) His church. He should be finding opportunities to love his family, serve his family, help his wife, care for his children, work for his family, etc. I also believe the wife should be doing the same. We should be working together to create the best, strongest, loving families that we can and teaching our children to be good, loving people who care and want to help others.
So, in short, a Christian man should lead his home...following the example of Christ. He should love his family with all his heart and put his family before himself. He should serve his family...all family members should serve/love/care about each other. Last I checked, Christ wasn't an overbearing, dominating, controlling type of person. No husband should ever be.
When it comes to decision making, that is a joint thing. IF by chance there is something that can't be decided on, I will at times default to my husband, but he does the same to me at times. It's called compromise.
But, any good leader knows to listen and care about those he leads. A leader serves those that he leads and loves. He should listen and consider their feelings/opinions equal or above his own. And, any married man better listen and care about what his wife thinks/feels. While I feel like my husband is the designated leader...I don't at all believe that means that my opinion counts for less than his. I guess I see it more than in the end, he'll have to answer to God for how he watched over his family (me too), and so he probably should make sure to follow Christ's example.
It's not a dominating thing. It's certainly NOTHING like what your husband thinks he should be allowed to do. That's just silly. Because he's a man he thinks he has the right to disrespect you and claim it's okay because he's a man? Yeah...no way. You sound like you have your head on right. Hopefully he'll figure it out a little bit better than he currently has it figured out!
And, sorry if this got a little too Christian-y. I just see it so much where the husband tries to claim authority and then dominates and is way out of line, and it drives me insane. And, also sorry if you're not Christian and most of this was a waste for you;-) Either way, though, that's how I view it.
