As someone who prefers to cook on my own due to having a very small kitchen and being a natural control freak, I can quickly pile on work for myself without realizing it. It's easy for me to forget I can just ask my live-in partner to help me chop something or watch a simmering pot while I finish my work. All to say: always ask! Even if you live with a total cooking novice, almost anyone can stir a pan of veggies.
Also, this goes without saying, but if you're cooking for someone else, you should NOT be preparing a meal and doing the dishes (unless they literally do every other household chore). If you're burning down anything in your kitchen, it should be that. 🙃
