how to be a stay at home wife?

okay this may be stupid but please just read.

i grew up where both my parents worked, but my mom ALWAYS cooked after work and did all the cleaning. idk how she did it but i know she did it for me and my siblings. well my fiancé wants me to stay home (if i choose not to work) and he’ll pay for everything. obviously he wants me to take care of the house since i’ll be taken care of. but i’m sorry are y’all really cooking 3 meals a day?? do y’all’s husbands not take care of ANYTHING? he obviously would do all the “man chores” such as trash, mowing the lawn, etc. i don’t mind cleaning but it’s the cooking part that gets me. i don’t even cook every week for myself so i’m just worried how to fit into this lifestyle. what do y’all’s day to days look like? without kids and with kids. i’m just curious
