Your problem is that you have a fantasy idea of what this girl is like.

You don't even know her.
You haven't spent enough time with her to be annoyed by all the habits or personality traits that would drive you crazy.

Ask her friends what her bad habits are.

She is probably very shallow .

You should quit fantasizing about gger and find a nice girlfriend, that doesn't already have a boyfriend that will beat you up.

Cheers
