He keeps introducing me as his wife and I don't like it?

He keeps introducing me as his wife and I dont like it?
I hate how when I'm with my man and we meet someone he knows and they ask if I'm his wife and he says yes.

This is upsetting because we are not married yet. He has done this thrice and I have told him I don't like it, but he did it today again and I got upset. And I see he is upset too cause I complained again and told him to just say I'm his friend. We are not talking to each other right now. I'm still upset. An I wrong here?
