'Martyr' Man

I have been reading the "Ode Less Traveled" By Stephen Fry. I am just trying to write in correct metre.

I've gone to work and left our life behind.
Our house, our son and you, my pregnant wife.
My friends commend me for my sacrifice.
They think I sacrifice! A holiday,
A chance to rest and have my time

But what a time you get to have my dear.
You clean the toilet, kitchen, stove and cook.
My word you cook. Breakfast and lunch and dinner
But not for one or two or three but four.
For you support your martyr man. And so
You should. Do not be so ungrateful dear
To question why your martyr gets his praise.
