There are conflicting statements in you post.
It says that in the initial application you were unemployed but later you say that you have had a business for many months. It also says that the business is not making money and therefore they see that you cannot support yourself without your partner’s support, so why would you return to a business that is not making any money.
Have you explained what will happen to the business while you are away?
A visit visa is always the most difficult to obtain and you must provide a lot of evidence with supporting documents and explanations as to why you should be approved.
You have not said what your long term plans are, if you plan to settle in the UK with your partner as either fiancé or spouse I suggest you forget the visit visa and concentrate on this type of visa.
