I'm going to expect my gf to cook and clean at home
Why do you expect your girlfriend to cook for you?
I don't wanna starve to death. I have the right to ask my girlfriend to cook at home.
You shouldn't expect your girlfriend to cook for you. Maybe you can ask your girlfriend to cook for you, or you could take turns. This way you won't have unhealthy expectations for your partner.
I expect my girlfriend to cook for me now. If she wants to be with me, she needs to be a slave.
Your girlfriend is her own person with her own life and does not exist to serve you. If you maintain the attitude of treating her like a slave, she's probably going to leave you. Learn to be more independent and more respectful of your girlfriend.
