How can I leave an house hold that is not suitable for my child

We have often offered this advice to women in your situation,and you are on the computer please Google women's shelters in your particular area if your situation is intolerable and you can manage. Please keep in touch with us until you do this.

I'm guessing that the word you were searching for is "environment".

In order to answer your question from a legal perspective we will need to know more. For example,

Are you married to, and living with, the other parent?
Is there a custody decree in place, and if so, who has custody?
What state or country are you in?
What is it about the household that makes the environment not suitable for the child?
