Is it reasonable to share a room with others and cook for others?

Personally, I feel that since you two shared a house, you said that your husband shared the rent with him, which means you paid less. Although you pay for the food and you don't have a cooker, you use others'. This account is actually messed up. Since you are unhappy, let your husband and that colleague straighten out the accounts, and you should pay more rent. There is no reason to share the rent equally, and others should use the cooking utensils. Therefore, people should not be given a bite to eat. There are only two kinds now, one is that you burn for others. One is that you should not be greedy of others, so let's settle the accounts clearly. He eats his food and you eat yours. Let your husband make it clear to his colleagues.
