That's fine, IMO. As long as you and your family are eating, who cares who cooks? :lol: You get to set your own priorities.
I think that's one of the things that really damaged my relationship with the ex. I love cooking. But he expected me to cook and saw anything food-related as my sole responsiblity. I didn't mind, at first, but once I started feeling taken for granted, the thing I used to love became a burden.
Structure your life in a way that makes you happy, IMO. There's nothing wrong with that. No guilt, sweetie.

Especially now that there are so many healthful options out there -- convenience foods from the supermarket (not fast food -- healthful food that's already cooked,) restaurants that deliver honest-to-goodness dinner, etc., there's no need to set your priorities such that you spend an hour a day in the kitchen, unless you want to. My two cents.
