Me too. If you want to talk about your "wife", "husband", "mate", "fuckbuddy", "boyfriend", "girlfriend", "housemate", whatever, I'm willing to use whatever word you think describes your relationship best. Well, maybe not "fuckbuddy".
It's just when faced with a large group of people -- or even an individual but relatively unknown person -- who have made radically different choices in how they organize their intimate relationships that I think "partner(s)" is appropriate. It would be awfully presumptuous of me to invite you and your husband to a party.
