Hi there,
There's no shame in letting your wife work and support the family financially. You can take care of the family as well by offering support, taking care of errands that don't require physical strain, sitting at the table, peeling veggies, that sort of thing. A good wife will do her part to take care of the family, even if it means working outside of the home. In this day and age, it is not only the 'man's duty' to be the bread winner. Once you are healed, you can go back to traditional roles if you like.
