I would say that your previous refusals will not affect your spouse visa application. Each application should by based on its own merits.
As the spouse visa is different to the student and tourist visa, in that you do not have to show reason to return or sufficent funds required for a student visa.
With the spouse visa you need to show its a genuine relationship and your husband had sufficient funds to support you without the need for public funds.
Dont forget to include all you previous visa submissions on you application.
We had a visit visa denied but got our spouse visa when we applied.
Good luck and hope you get your visa soon.
