Your case is a complicated one for we haven't got a consistent refugee politc in the EU.
What is your status in Germany? If your husband has got residence for 5 years in Denmark you have the right to move there after 3 years. If you have a comparable status in Germany a familiy reunion might be merely an administrative problem.
Anyway, ask the expertes of Pro Asyl for help, they are experienced in such cases.
