Sometimes you can’t make it work. But if you are relying on her income, you need to acknowledge that right now the work you are doing on your startup is essentially a hobby until it is making money or you get funding. A spouse is unlikely to be ok with their partner just focusing on a hobby and not contributing in other ways. So find ways that you can contribute. Do the cooking and the cleaning and other house chores, and then find time to work on your startup when you’re done with those.
