My parents taught me that a good woman should marry a man. Then she can have children. But I don’t want to get married. Am I a good woman?

In Germany, people live together in many different ways.
Here are a few examples:
Some men and women are married and have children.
Some men and women have children and are NOT married.
Some men and women are married and have NO children.

Some couples are separated or divorced.
That means that they have ended their relationship.
Some of these couples have children.
The children might then live with their mother or their father.

Some men and women are homosexual.
They might be in a relationship with a person of the same gender.
Some people live in shared accommodation.
That means that they live together but are not in a relationship or a family.
Lots of men and women also live alone when they are adults.

Everyone can decide how they want to live.
All of these options are permitted in Germany.
Nobody in these examples is good or bad.
And nobody may be discriminated against or prosecuted for this behaviour.
It’s okay if you don’t want to get married.
You are not a bad woman.
