> I expressed my disappointment to her twice, but out of nowhere, she became angry.

so your GF cooks for you and you bash her when she does? What is the best course of action? how about not bashing someones food when they make it for you. You sound like a douche. I like how you premise the whole thing with 'postpartum' GF, you know really try to put your shitty communication skills on the back burner and make it about how your GF is someone inherently in the wrong.
