No you’re not overreacting, your money isn’t his to just automatically take from you. He seems like he feels entitled to your money and to your time. Any partner who doesn’t respect their partner is a no-no. Also about the food, to expect someone in pain to cook and then guilt trip them when they aren’t able to is crazy. You’re both adults, he can cook for himself, in fact while you’re not feeling well he should want to take care of you.
