Who ever told you that life is fair? Seriously? I must have missed that memo...
You are starting to come across to me as an angry petty man who is hellbent on punishing his wife because, *gasp*, "how dare she do this to ME!"
Personally, I don't see how $28,000, albeit not chump change, is pocketful of money. You are still going to retain the marital home. So, you have to buy her out? That is not being selfish. I think you might want to talk to an attorney and see what they say about a settlement before she demands full disclosure about every facet of the family business. Just thinking.
Before you get too angry with me, I am going to say that I see a lot of me in the way you come across (ripping off those rose colored glasses) before I came to my big "AHA!" moment. It really caused me pain to look at myself realistically and honestly and see someone I really didn't like and someone I did not want to be any longer.
