However, the state doesn't validate relationships

Apparently and sadly, it does now.

Throughout history the "state" (ruling government) has sanctioned martal relationships. This was to ensure consitency of inheritence laws, property ownership, and paternity/maternity.

If same sex couples wish to have a live in relationship they can go and have a co-habitation contract drawn up identifying inheritance rights, health care authority, etc.
