Name Drama

Nicole
Why do people think it's okay to give an opinion on the name you pick for your baby? 
I am naming my baby girl Jenavev. Pronounced like Genevieve. Jena for short. I've heard "good luck teaching her to spell that, and you know she has to put her name on papers? And you can just go making up names." 
Now my boyfriend is feeling inconfident in the name we chose... stressing me out. People are stupid.
