How Do I get Out of Brother-Zone?

A girl who I have a crush on has me in her bro zone... how do I get out of it. (I'm not that good looking. I'm just average with a little fat around waist, technically I'm an average looking fat guy ) I am worried about what she might think If I just break the thing to her.
