You sound like a jerk. Why would you even ask that? Don't expect people to change. If you don't like the way they are then just leave. There are other people out there that will be good with your daughter and make good money.
What the fuck fairy tale do you live in?
Nobody is perfect for anybody else.
If you care enough about someone, you change something for them.
If she values you more than her weight(moreso, more than being fat and eating when she wants), she will at least try.
Likewise if she said "you're almost perfect but you're overly blunt and rude af." Well if you value her more than you're rudeness you'd change (well chances are you'd not change, you seem narcissistic though I could be wrong. So you'd probably defend yourself and start a fight over changing for someone you supposedly love)
I'm here learning things to be the perfect wife for my husband. When I get that close to someone I'll change some things for him if he doesn't like certain things that are within my realm of control. Except I won't get fat for someone if he has a fat fetish because I reall value being healthy and liking how I look
I thought it was all about accepting your partner as he/she is, not changing that person to match your dream partner. ---
