What is better, to use both names after marriage or retain the maiden?
The better name for you is the one you feel best suits you for your life going forward. How do you wish to be thought of? What name would you prefer using to introduce yourself in EVERY situation. Your name is a big part of your identity. You get to decide how to act, speak, write, play, dream. You also get to choose what to be called. Think of what youd like to be called when you are your best version of yourself. Thats the name you should take. Put that name on your passport and everything else. That name is you.
