AITA for not cooking for my husband and eating our leftovers?

Hello reddit. This is my first time writing a post. So here is my question, am I the asshole for not cooking for my husband and eating the leftovers with our kids?

So yesterday after work I picked up our twin girls from Kindergarten and started to cook right away. While I was cooking, my husband laid on the couch and was scrolling trough his phone.

So today when I got home from work, me and the girls ate our leftovers. When my husband got home, he was very angry with me and we started arguing. He said things like "you are egoistic to eat all by yourself" and why did i not cook for him.

For some context, I work almost full-time and have school 2 times a week. I study for my exams and try to keep the house and children clean. We have 3 kids together and got together when I was 15 and he 19. Now I am 29 years old.

I do feel guilty, maybe I just had to cook something for him or later for me...

I'm sorry for any grammar mistakes. I don't live in an english speaking country.

Thanks everyone for reading and have a wonderful day :)
