What are your plans for after the business is dissolved?
If I were your wife, I would want to see you aggressively pursuing what comes next, in the form of sending out resumes and putting together a plan of action. I abhor uncertainty. I'm sure this has to do with growing up in the manner in which I did and I also left home at an early age. I can tolerate pretty much anything with regards to my husband's job plans, except indecision and uncertainty. I need to see him strong and capable. He is not always this way but that is my own challenge to work through.
With how you relate some of your convos with your wife, I can see how she would feel controlled. NOT that you are consciously trying to do that, but just in the particular communication patterns you employ with her.
I can't say what you should do about that, except to perhaps read some communication-in-relationships type books. I know lots of people love mars/venus but I personally hated it! Gottman writes really good communication books and I found them very useful and helpful, even to this day.
My H used to be controlling himself and it wasn't until recently (say, within the last year) that I have recognized it as a lack of communication skills coupled with fear--and not a desire to control, necessarily.
