Husband or Wife?

[silverfoxcc]

Following the legalisation of same sex marriages, i am getting a little confused on who is who in these.
I have seen Stephen Fry refer to his partner as his Husband,so what is Fry if the terms of Husband and Wife is being used. also in two Woman/Woman marriages recently i have seen both husband and wife being used to describe the other partner.

Could someone explain how it is established in a marriage,is it physical or mental i would like to konw as my sons friend is in a relationship and i just want to get it right should it crop up,forewarned etc
