Yes, and I'm also aware there was some series just prior to Nu52 Batwoman, I think, that had a male/female couple and I think they were in our world, not Kandor.
My ultimate guess is that if you have a NightWing and Flamebird on the table, they seem to be a couple, but editorial doesn't want Dick with Bette, for whatever reasons.
Despite the idea of the triangle that many comics stories employ, they won't bring her back to her rightful place.
So, maybe they should make Barbara Flamebird
and let Betty go back to being THE ORIGINAL BAT-GIRL
because she was, and I won't ever let them forget it.
