It means that he take the decisions ? is there a saying in English?

In this house I wear the pants.

The one who wears the pants is the one who takes charge/makes the decisions in a household.

Or you could use a more benign "I'm the one who's in charge in this house".

Yeah, unless she who wears the pants tells you otherwise. :)

And that is my case exactly!

I wear the pants, but my wife tightens the belt...;) :D :lol:

You guys make me laugh. :)

Another observation from the opening post: In North American English, we say "to make a decision", and I believe in British English, they say "to take a decision".

En España tambien se dice llevar los pantalones.
