You mentioned that you have no income for therapy. How are you surviving? Is he paying you an "allowance" to cover your expenses? Are you completely dependant on him financially as well?
I cannot stress enough how important it is in your sitch to see an attorney. You have contributed to the business, been told you are a partner, etc. You need to protect yourself!
If you do learn your options, I think it will help you GAL. And, he may take you more seriously.
I would also suggest you start thinking about where else you might be able to find work and start preparing for that by updating your resume and starting to network. It feels to like your work sitch is going to keep you from GAL.
My two cents.
