i feel embarrassed

my bf is mad at me because i can’t cook? like i feel embarrassed bc he was cooking and his brother was like she’s just standing there watching him cook :/ idk i’m only 18 and i feel like he wants sum wife (he’s 23) it’s not that i’m bad at it i just literally don’t know how. my mom would always tell me to go away while she was in the kitchen and idk i just never picked up on it :( i feel really embarrassed now
