I agree with the others - you need to set clear rules/boundaries on this type of thing. Perhaps a division of responsibilities would be in order? Although my wife is part of my company, she has no control over it's management, though I do value her input and do seek her opinion on major issues. I only say that as an example; obviously, in your case there is more active involvement by your wife, so allowances for that must be made.

Also, it would be a good idea for her to not only read the responses to your post (no sense in hiding!) but also to have her participate in the forum and perhaps speak to some similarly situated people. What about the franchisor - do they offer any resources to help with something like this? Maybe you can check in the franchise board for additional assistance, as franchisees may have a different set of issues than those of us who are not.
