Did you have to bash Lavender in this chapter? Ron is utterly worthless as a human being, wizard, canon fodder. There is no reason for Lavender to be infatuated with the piece of trash.
Hopefully in a future chapter, she'll dump him like the bad habit he is.
Author's response
In the long run, Lavender will be the better match for Ron. Yes she is somewhat shallow, but looks fade and I can see Lav getting comfortably fat while minding the next Weasley brood.
On a personal note, my High School crush, Miss Unattainable, Nineteen Seventy Something, at our ten-year reunion was still single and had morphed into the shape of a beachball.
Meanwhile, my wife, plain and ignored by her HS classmates was the bell of the ball!
God I love irony!
