Wont cook

Ok so im 18 n have a 1 month old n my bf is 21. Recently hes been getting mad n saying that i dont cook so what does he want me for. Ive never had a bf before never cooked for anyone before just myself n only basic stuff. I kinda get that i should cook now that i have my own family but what pisses me off is that he said he needs a woman not a little girl. I was like wtf u shouldve found someone ur age then. Am i being dramatic :\
