While I'm personally happy that the marriage didn't happen, not only because I utterly hate the pairing but even more importantly I think it would have caused issues with future creative teams, the way it is done here is really, really weird.

I think a partial issue is due to King's focus on presenting Selina as the perfect woman, which has narrative impacts like this, but I also continue to be confused on how little agency Batman really has in King's run. Like here, it doesn't really strengthen the tragedy of being Batman when someone else basically decided that you can't be happy while being him.
