NAH

Vampires have a tradition of biting human partners at their wedding, but humans don't. In fact, we have a tradition of wanting to remain living, healthy and whole, inherited all the way back from reptilian ancestors millions of years ago. You seem to have respected that just fine until now, you even came to talk about how you are aware of it. Humans also happen to often have strong opinions on traditions.

For some reason, you assumed she would be okay with being bitten and she assumed such thing wouldn't happen. I'm sure you both worked past a lot of things to get your relationship to this point, and this takes both, all the differences considered. Just keep in mind she didn't disrespect vampire traditions, because she is not a vampire. Unfortunately, she can't both be transformed and not transformed so one must give. On the other hand, humans are comparatively short lived and fragile so do make sure you know what she actually wants you to do regarding her health moving on - bodily autonomy is fundamental. Disrespecting that with any partner would make you a huge AH.
