I wouldn't focus on the business, I would either move ourself and your daughter out of the house, or tell your wife she has to leave if she's drinking. No matter how good you are as a father, your daughter is being damaged living with her mother. I drank for only 4 years or so, but my daughter told me the other day how,she could never make mistakes, because of all the fighting between her father and I, the dog rescue I was doing, and the drinking. Get her away from her mother right now.
Peace,
Nancy
