I plan to tell my husband that I am not trying to divide the house chores any longer.
What is your reason for not wanting to divide the chores equally anymore?
I saw a video about animals being killed for food and I'm not longer comfortable cooking anything but vegan food.
You should still share the chores. If one of you doesn't want to eat what the other has cooked you can make your own food.
I don't want to split chores with someone who doesn't want to be vegan with me because it's cruel to the animals.
Even if you want to start eating vegan, that does not mean that the chores should no longer be divided. Sharing household chores is important because it keeps the balance of the home and also makes sure everything is up and running well.
