If a female friend has (jokingly?) asked if I want to be her girlfriend many times in front of others?

... and says we're in a relationship, refers to me as her boyfriend in a conversation (maybe half serious), but also sometimes says we're besties. Is she actually interested or just playing around as a friend?
