I misspelled my fiancee's name
How could you make that mistake? Have you ever met your fiancee?
No, I have never met her. She is pretty much like a character from a game to me.
That's funny.  It is ok to make a mistake sometimes with a challenging name.
She doesn't even feel like a real person. I mean how can i know she is a person for sure if I have never met her.
It's fun to fantasize like that, isn't it? It's okay to have made such mistakes, it's not your fault to. Just be careful on taking the fantasy too far, wouldn't you want to find someone to love for real?
