its a bitter sweet pill , without digging to deep I have just 1 suggestion

reoutline your business plan if you place value on your wifes concerns

there is always room for improvements in any business, and you should be able to bring some of your work home possibly, though this may not be the answer

modern technology is so advanced I have noticed that alot if not most very successful businesses have absentee owners, though usually that absentee fact is also the weakest link of the company in this economy....go figure

you should be able to manage some time in, or you might be micro managing your own company I do understand the fragile nature of business, I am not saying this is what you are doing, but it is comman in very small business and part of the reason they stay small imo

though alot prefer it that way
