Is it normal my girlfriend wants a nose job but i told her not to get it?

From what you just said, it ssounds like a nice way to say you have a big nose. "It gives you character", she mightve taken it the wrong way.

Does she have a beak

Tell her that if you had her nose full of dimes you could retire.

Tell her, that she if she has all that money lying around, she should spend on something more fun or useful-like a fancy vacation or a down-payment on a house. She already has a nose. She doesn't need a different one.

You called her Toucan Sam!

I would've said something similar, maybe not in the exact same words. The grass isn't always greener on the other side. There's no guarantee surgery will make her nose look any better.

why waste money on the nose? put it straight in the tits

Tell her if she gets the surgery that she has to bring the extra parts of her nose home with her in a doggie bag.

Just tell her she looks the most beautiful just the way she is and you wouldn't want to change the way she looks for anything else
