Thing is, Diana's the wrong character for that. Silver and Bronze Age Diana, perhaps; she was disturbingly concerned with romance. But Golden Age Diana and especially reboot Diana is not that kind of character at all. Clark? Clark is all about the true love. All those stories where he pines and never moves on from Lois after millennia in the heart of the sun or whatever, those make sense, because Clark is a very romantic character. But Diana is way too independent for that. I can no more believe her being forever crushed by losing her true love than I can believe it of Bruce. Less so, in fact, because I can't even believe her having just a single true love. I'd believe her going to crazy lengths for someone she loves deeply enough in a moment of sufficient uncertainty and desperation - I totally buy her compromising herself to try to rescue Polly in Gail's current plot, frex - but a calm, measured decision made with full faculties to permanently abnegate any part of herself for the sake of a single lover? No. Which is where it starts to feel sexist, because it seems like the "girls are all about the romance" stereotype is overwhelming any actual consideration of the characterization of Diana as an individual.
