think my bf is giving me PPD

i think that my boyfriend is giving PPD my baby boy is 9 days old today, and tbh i couldn't be happier he is such a healthy and good baby. i couldn't have asked for a better baby, my labor was bad but he makes it all worth it. whenever it's just the baby and i, i'm so happy we just hangout snd watch tv smd eat. whenever my boyfriend is home i feel like i have to walk on eggshells. he's told me everyday since we got the past 7 days that i could leave and he wouldn't care. he criticizes everything i do and everything i do is wrong. everything that goes wrong is all my fault. he tells me "all i need is him i could care less if you were still around you might as well leave" and other comments like that. i've hardly been eating, and i know i need to eat for the breastmilk but i'm never hungry anymore. i just feel sad like everyday is dragging on and i could never do anything right. it sucks and i don't know what to do
