How do you define 'family' and has that definition evolved over time for you?

Family is family, shared by blood or in some cases, adopted children become your family too.

Married people who may also have children together.

A family is simply a stable unit for cohabiting or parenting.

A family is a group of people who are associated together either through blood relations or legal bounds.

Yes. It has evolved over time for me. I no longer believe family is based on a martial status. Family is who you spend time with and who you would stand up for. I would not say that family is based on marriage.

The definition of family is defiently in need of expansion from the Constitutional definition.

My family is my family, everyone who is related and some people who are not, but that does not mean I have responsibility for the welfare of my whole family, just my immediate family. I will always help where I can but the help will never come at the cost of niglect to my immediate family. Parents, brothers, sisters, partner, children and eventually grandchildren are my immediate family.

Yes it is no longer nuclear family is anyone who loves and supports you

You can't chose your family, but you're family isn't conventional. It's who cares for you
