If you are living exclusively together long term you are effectively married even if you don't have a paper saying so.
Some states call it common law marriage, but even if they don't you are still effectively married.
Marriage is not a piece of paper, marriage is a family structure.
on what basis?
My partner and I had our 3 children out of wedlock. Who are you to say that unwed parents is a lock-in to food stamps and crime?
Next you'll be blaming unwed parents for the break down of the fabric of society.
You are way out of line.
