This is a tricky one. If you need a salary and he doesn't, it isn't fair to you as you are in a position of need and he/she isn't. I would be reluctant to give any equity back, try to negotiate with your partner. Perhaps you should both take a salary? Your co-founder needs to be empathetic to your needs, regardless of his or her own lack of need. This is a good test of your relationship. Obviously if the other founder doesn't need money then they are either financially well off (you should get paid) or they don't have any overhead or personal expenses, as in they live at home with parents (you should get paid).
