My fiancé is great, obviously. But her refers to me as his "bird" and other people in the same way, eg.
"Fred is a great guy, he really loves his bird."
I called him on this and asked him to stop doing it and he appeared baffled and asked: "Well how do you want me to refer to you then?" I said: "Well you know o call you your name, or my fiancé, why not do that?"
He thinks I'm being OTT and making something out of nothing. AIBU to be irritated by this?
