I completelly respect your opinion, but I don´t agree. I guess this is becouse of the differences of our cultures.

I must say that women have as much rights and power as men in a family. Giving her less importance only because of her gender is completely unfair. It happens the same with ethnicities. We born in certain place in certain conditions that we must accept as they must do the other people.

In conclusion, I believe that both men and women must take decisions in a family. One would be better than the other doing certain things, and between them, they should take a decision about who is gonna do each activity, because both of them are part of the family. One is nothing without the other.

As I said before, I respect your opinion and I don´t want to hurt anyone.

If there is any mistake, let me know to learn

There is a saying in Russia: a man is a head, a woman is a neck. Where the neck will turn, there the head will look:)

To be serious, it's good if a man feels that he is responsible for his family, but it's bad if he makes decision without woman's agreement on that ground.

In the English-speaking world, the plain fact of the matter is that most families have a complicated power structures. There isn't any single leader with 100% control. Even in the most "traditional" of families, the wife has areas of authority. And children are not by any means powerless. 

So someone who thinks that "a man should be in charge" is preparing themselves to be unhappy, because they are never going to have a life that is in harmony with their ideas.

If you are not currently married, it is best not to form a rigid idea of what your married life is going to be like. People are individuals. Life does not fit into neat patterns. Until you are actually married to one particular unique person, you cannot even begin to guess what your one particular unique married life will be like. It is not going to be simple! Anna and Alina are completely different, and a marriage with Anna will be completely different from a marriage with Alina!

Even if you feel very certain that "a man has to be in charge and make the most important decisions," this is something you need to discuss with a fiancee. Don't assume that she agrees, just because you think that is what marriage is. Don't assume anything!

And you might check the words of the marriage vows in your tradition! In the United States, and I imagine in Ukraine, at a wedding, the couple exchanges "marriage vows." These are solemn promises. 

In the Anglican tradition the vows have had a complicated history. The bride has sometimes promised to love, cherish, and to obey," but there have often had alternatives that the couple could choose. The Episcopal Church marriage vows have not included the word "obey" since 1922.
