Gotta say I like Dave's idea too. Let him know calmly that you feel yourself getting angry when you do things for him in the role of wife (under present circumstances) and, to prevent yourself from becoming increasingly resentful, you are going to ask him to take care of his own household needs. You could even suggest that you split up certain chores or sections of the house. You don't have to make it about him and his behaviors unless he asks why you don't feel like being in that role anymore.
