I'm thinking of pressuring my SO to quit her job
Are you serious? Why would you pressure her to quit?
She gets home too late to cook
It's selfish to pressure someone to quit their job just to make things easier for you. They will end up resenting you for ruining their career. They'll likely break up with you.
I will make it worth the sacrifice.
I just think you should let her work her job if she enjoys it there. Maybe you should start learning how to cook so you can cook for yourself?
