un-girlfriend

A girl who can not agree or disagree to being called your girlfriend and likes being celebrated every day as your girlfriend, (as Alice in Wonderland celebrated her un-birthday 364 days of the year) but is reluctant to accept the label of girlfriend because she is in denial of being someone's bae and non-committal to a stereotype she has clearly become and not been since high school.

One day before meeting up with friends, I asked "the girl I have been dating" how should I introduce her, suggesting that we are past the friend-zone. She jokes with a smile, "how about with un-girlfriend?" and kisses me on the cheek.
