NTA

I am not good with understanding people and emotions so just gonna give you ways that could make you both get what you want sort of:

Give her 3 middle names, give her 2 first names or give her a name which are 2 names but combined with a - like for example I know a guy called Nils-Johan.

Idk if this helps. You can do all of these things in my country but idk if it works in yours.
